Thirty Days (episode)
Tom Paris is demoted to ensign and is sentenced to thirty days in the brig for disobeying orders. While serving time in the brig, Tom writes a letter to his father about the events that led to his demotion.

Summary

Teaser
Captain Kathryn Janeway, stands in her ready room aboard the vessel, face to face with her chief conn officer,  Tom Paris. Two security officers are present at the door. 

Janeway regards Paris sternly. She pronounces his full name and her punishment against him: demotion to the rank of ensign and incarceration, in solitary confinement, for the next thirty days in the brig. Paris stands at attention, staring straight ahead. She reaches for the two pips on his collar, one black and one gold, indicating his Lieutenant Junior Grade rank, and plucks the black pip away, leaving only the gold one, the insignia of an ensign. She then orders the security officers to escort him to the brig, referring to him by his new, lower rank.

The officers advance, but Paris shrugs them off, telling them he knows the way. He turns briskly and leaves, the officers behind him. Janeway stares silently at him as the door closes behind them. He marches along the corridors, the officers behind him. He looks neither right nor left, as passing crewmates pause and stare, some with great concern, particularly his girlfriend B'Elanna Torres. He enters the turbolift with the officers.

Arriving alone at the brig, they enter. They stop at the "turnkey station," where Paris removes his combadge and surrenders it to the officer on duty. He enters a cell. The officer activates the cell entrance's force field, sealing him inside. He lies down on the bunk at the back, and does not move again, breathing slowly, preparing to accept his confinement.

Act One
Paris has removed his uniform jacket and undershirt, leaving only his T-shirt during his first day of being in solitary. A security officer is on duty, monitoring him as Paris begins to do some push-ups. Neelix enters with a tray of food consisting of only basic nutrition. Paris complains, but Neelix responds that the captain has ordered he receive only basic nutrition for the duration of his incarceration. Paris then asks him about his request to the captain for time on the holodeck, but he is again disappointed; she has denied it.

Neelix then turns to leave. Paris asks him to stay and talk, but he replies that the captain's instruction is: "No nonessential conversation with the prisoner."  Paris muses whether the words "cruel and unusual " mean anything to Janeway. Neelix sadly leaves him alone. But Paris has been provided with a PADD for him to 'write' with. He picks it up from the food tray and sits down.

Paris begins to dictate on it a letter to his father, Admiral Owen Paris, although he has no idea if he will ever receive it. He also knows his father, who he believes never thought much of him, will probably not be surprised to hear that he is again in jail. So he begins to describe the circumstances that led him to the brig in detail, so that his father will know that this time the reasons for his incarceration are different. ()

It started, he begins, on a morning that found him doing something he knows, he dictates, "you would find a complete waste of time." He is seen playing Captain Proton on the holodeck. In this adventure, he is joined by his usual partner, Operations officer Ensign Harry Kim, playing Proton's sidekick, Buster Kincaid. Also joining them, playing the part of the villains Proton must defeat, The Twin Mistresses of Evil, are Jenny and Megan Delaney. 

They are interrupted by a hail from Commander Chakotay, ordering all senior staff to the bridge. They leave and Paris and Kim quickly obey, not bothering to change out of their costumes.  On the  bridge, Captain Janeway informs them that a very strange reading has been picked up on sensors: a celestial object that is not a planet, but teems with life. Paris and Kim go to their stations.

The ship comes within the sensors' visual range of the heavenly body. Janeway orders an on-screen view. It is a planet-sized globe made entirely of water; literally, a "world ocean." There is no land at all anywhere in its composition, only water. Kim scans it and reports that a containment field is holding it together. Paris gazes at it wonderously.

Suddenly three small ships burst forth from the surface and rush up toward them. Janeway orders an attempted hail, but they do not respond, instead, firing on Voyager. Their weapons do no damage. She calls a red alert and again orders an attempted hail. But again the only answer is weapons fire. She orders Tuvok, the Vulcan chief tactical officer, to return fire, targeting the lead ship's weapons. He does so, disabling them. She again orders an attempted hail. This time, they respond. 

On the viewscreen appears an alien wearing a jacket and a hooded undercoat. He identifies himself as Deputy Consul Burkus of the Monean Maritime Sovereignty. He orders Janeway to withdraw. She responds that she and her crew mean them no harm, explaining that they are explorers and are simply fascinated by their "world ocean," and would like to learn more about it and them. She points out that Voyager could have easily destroyed them all, but has not. Burkus accepts this, noting the impressiveness of Voyager. Janeway smiles and offers him a tour.

Janeway, Tuvok, and Neelix take Burkus and a party of his people, called Moneans, around the ship, ending in a visit to the bridge. Here Neelix asks them if the Moneans have always lived in this "world ocean," which the Moneans call The Waters. Burkus responds that their ancestors found it three hundred years prior, and decided to settle there, farming aquatic vegetation and extracting oxygen for their ships and undersea settlements. The group leaves, but before it does, Janeway invites Paris to join them, which he is more than happy to do.

Voyager orbits The Waters. In the briefing room, the Moneans explain further about The Waters. Riga, another of the party, tells them they have no idea how The Waters were formed, but he theorizes that they formed in the way a gas giant does. 

But, he explains further, their lack of knowledge about its formation has led to problems: it has begun to shrink, as the water has recently begun to dissipate through the containment field. They believe the answer to stopping the loss is to be found at the center, six hundred kilometers down, but their ships are unable to go down that deep. Paris enthusiastically (and inappropriately, earning him a surprised and somewhat irritated look from Captain Janeway), tells them that Voyager can help them do so.

Later, in her ready room, Janeway sits informally with Paris, having tea. She asks him about his enthusiasm in assistING the Moneans save their "world ocean." He replies that he has always had a keen interest in the sea as a child, back on Earth, even wanting to join the Federation Naval Patrol. But his father was adamant that he be a Starfleet officer. He suggests a few adjustments to the  which will make it capable of submarine operation. Janeway approves, putting Paris in charge of the mission.

The Flyer is made ready. Paris and Ensign Kim make ready to depart, along with a third crewmember, Seven of Nine. Also accompanying them is Riga, one of the Monean party. The Flyer leaves the shuttlebay and, after a quick final systems check, Paris, the pilot, puts it into a controlled nosedive. It plunges into The Waters, disappearing beneath the surface.

Act Two

The Flyer descends into The Waters. It passes a large, active industrial structure, which Riga identifies as one of their oxygen refineries. The Voyager crewmembers find it most impressive. Paris gazes at it in wonder.

Captain Janeway is in her ready room, looking out her windows at the surface of The Waters. First Officer Chakotay and Deputy Consul Burkus enter. Chakotay reports to her, in Burkus' presence, that the rate of water loss is worse than previously thought: the entire "world ocean" will dissipate in less than five years. They may have to consider evacuating if a stop is not put to the loss. Burkus doubts the accuracy of the data, and having to report this projection to the members of the government, the 47 regional sovereigns. He believes they'll pass a resolution demanding his political head. Janeway insists that telling them is the right thing to do. Burkus responds that he will wait and see what the Flyer finds first.

The Flyer is five hundred kilometers down and still descending. The hull creaks a bit, to the consternation of Riga, the first Monean to be at these depths. Kim assures him all is well, and makes a few adjustments to the controls. The creaking stops.

Then Seven detects a structure twelve kilometers away. This shocks Riga; what structure could there be at this depth? None of his people have ever been so far down, so it cannot be theirs. Paris heads for it, turning on powerful external headlamps so they can see it out the windows. Kim scans it and surmises that it is a field generator; this may be what is generating the containment field that is keeping The Waters together. Even more shockingly, its age appears to be over 100,000 years. Kim finds that the thing has a computer system, and begins downloading its database.

But then a shadow passes. An immense aquatic creature, eel-like, and much larger than the Flyer, appears. It is a predator by the look of its mouth, which is rimmed with dagger-like teeth. Like the Earth fish known as the electric eel, it discharges large amounts of electricity that begin shorting out systems on the Flyer. Riga has no idea what it is; not having been at these depths before, his people have no idea what lurks down here. Seven, however, uses a few shots from the shuttle's phasers to convince the creature to find easier prey. 

However, the damage has been done: they have lost propulsion and shields and are leaking.

Paris sits in his cell, recounting the incident, as the PADD records it. Suddenly, Voyager is shaken. Janeway's voice comes over the com, sternly calling red alert and ordering all hands to battle stations. The officer on duty quickly departs. Paris calls after him; if the ship is under attack, he, Paris, the conn officer, should be on the bridge at the conn station. But the officer does not respond, and a second jolt throws him into a wall, almost knocking him unconscious.

Act Three
Paris comes to and finds The Doctor over him, ministering to his injuries. They are not serious, no more than a bump on the head. Paris gets up, sits on the bunk and asks him about what happened. 

The Doctor informs him that they were attacked by five ships. He then takes the opportunity to frighten Paris, for all the times Paris has annoyed and exasperated him, by telling him about the sterling performance at the helm of Ensign Culhane, who has temporarily replaced him as conn officer. He twists the knife even further by suggesting that Captain Janeway may be considering making the appointment permanent, from what he has heard.

Finishing his ministrations, The Doctor packs up his medkit and turns to leave. Paris pleads with him for a neurological scan or something, to get him a medical reprieve and an early release; the confinement and isolation are getting to him now; he has been here for ten days and has twenty more to go. But The Doctor refuses and tells Paris that he will see him in twenty days.

After he has gone, Paris sighs, returns to the bunk and resumes dictating his letter to his father. He is seen in the Flyer fixing leaks. He is soaked. The leaks are plugged, but without thrusters, the only way they can surface is to jettison what they can to achieve positive buoyancy and float up. However, Paris insists on staying; this may be their only chance to study and fix the containment field generator. Kim strongly disagrees, given the state of the Flyer. But Seven also decides that they should stay, and so Kim goes along.

Aboard Voyager, on the bridge's viewscreen, a disturbance appears on the surface of The Waters. A huge column of vapor extends from the center of the disturbance, into space. Tuvok reports to Janeway that it is a containment field breach. She orders measures taken to stop it.

Burkus asks her about the Flyer. She has no ready answer, as they have been out of contact for a while, but not long enough to be alarming. Burkus becomes flustered, wondering aloud what he is going to tell the council.  Janeway asks him which he cares about more: his political career or the lives of the people on the shuttle trying to help his people. He does not answer. 

On the Flyer, Kim, who along with Seven, has detected the breach on the sensors, finds, however, that it was not a malfunction, but done "deliberately" by the field generator. He finds that the density of the water has been increasing over the past few years, and the generator is periodically creating breaches in the containment field to release the building pressure on itself, to keep itself from being crushed. Paris surmises that they can boost its power using the Flyers power cells, thus enabling it to handle the increasing pressure without releasing water. Seven agrees, but cautions that the effect will be only temporary. They carry out the procedure, and then begin floating to the surface.

In the Delta Flyers aft section, Riga finds Paris working at a computer console. He has found information that shows that The Waters used to be part of a land mass; they were the oceans of a planet that was home to a very advanced civilization. It is unknown what happened to them, but they were the ones who created the generator. They launched it into space and it kinetically drew all oceans unto itself, along with all life in them.

Riga is stunned and asks Paris why this civilization would have done such a thing. Paris can only guess it may have been due to an impending disaster or possibly an experiment. Paris also tells him the generator's periodic dropping of the containment field is not what has been causing the water loss. It is the Moneans' oxygen-mining operations.

Paris lies in his cell, having an unpleasant dream about his father scolding him and sending him to his room for playing with ancient sailing-ship models, instead of doing his homework. His father's voice morphs into Janeway's voice, speaking her punishment against him, but she says thirty years not thirty days in jail. The unpleasant dream fades away, however, as Ensign Kim, who has come to see him, wakes him up.

Paris now looks as haggard as he feels. His face is covered with stubble, and he looks disheveled. Captain Janeway has finally relented a bit on allowing him visitors, but has ordered Kim to keep it to a few minutes. Paris has fourteen more days to go.

He asks Kim about his, Paris', girlfriend, Lieutenant B'Elanna Torres. Kim responds that she misses him. He asks Paris what he has been doing to pass the time. Paris tells him of the letter he is writing, but he is unsure if he going to finish it, or wants to. Kim suggests that Paris should finish it. But Paris does not want another lecture, and asks him to leave. Kim does so as he tells Paris that he will see him in fourteen days, with the parting comment about him proving his father right: he never finishes what he starts.

Act Four
Paris continues his letter, recounting the presentation of his findings to Deputy Consul Burkus. He, Janeway, and Torres are in the briefing room discussing them with Burkus and Riga. The Starfleet officers offer to provide alternative oxygen production technology to the Monean government, but stress that the oxygen mining must be cut back or cease, to stop the water loss and save their world. 

Burkus diplomatically promises to take the findings under advisement, although displaying no real ntention of doing anything about it. His only concern is the political backlash against him for recommending that the mining operations be stopped. Paris sees this, and begins to angrily remonstrate with him. Burkus leaves in a huff. Riga follows sadly. Not being a senior official, his hands are tied. 

After they have gone, Janeway angrily rebukes Paris. She stresses that, according to the Prime Directive, they can do nothing else to help. Paris' response borders on insubordination. At this, Janeway dismisses Paris and very angrily warns him to "check the attitude". She stresses that she agrees with him, but they can do no more; they cannot force the Moneans to accept their recommendation. She tells him they will soon be departing. He acknowledges but remains upset. He goes to the holodeck and has the computer activate the "Captain Proton" environment, but without the characters. He sits glumly in the simulated bridge of Proton's ship. Torres enters and sits with him. He resignedly tells her that he had thought that this would be the chance to revisit his childhood love of the ocean on a scale he could not ever have imagined as a child, but finds himself unable to save this world ocean. Torres tells her that no matter what, she's proud of him for finding something he cares so passionately about, and asks if Tom Paris can take action where Captain Proton cannot.

Paris goes to one of the transporter rooms and finds Riga preparing to return to The Waters. Paris dismisses the crewman at the controls and asks Riga what would happen if the oxygen refineries were damaged. Riga states they would be rebuilt, but Paris guesses that if they were then they would likely be redesigned to cause less damage to the ocean. Riga realizes that Paris is more than willing to take this action, and is ready to help.

Captain Janeway arrives on the bridge in response to an urgent call from Tuvok. He informs her that the Delta Flyer has left the shuttlebay, without authorization. She immediately knows who has taken it. Aboard, Paris and Riga are grim-faced as Paris takes the craft down and nosedives it into the water.

Act Five
On the bridge, a hail comes in from Deputy Consul Burkus who tells Janeway Monean sensors have detected the Flyer. Janeway informs him who the occupants are, and tells him her assumption that they are planning "to take some sort of... radical action to protect the ocean." Burkus agitatedly voices his hope that she is planning to stop them. Her angry glare is confirmation that she intends to do just that, and she ends the communication.

Beneath the surface of The Waters, three Monean ships fire on the Flyer, but Paris' expert piloting skills makes the Flyer easily escape them. A hail comes through from Janeway who orders him to return immediately. He refuses, his voice sad. Janeway informs Paris that he is disobeying a direct order.

On Voyagers bridge, Chakotay reports with disbelief that Paris has cut the communication. Kim reports that they seem to be heading for one of the oxygen refineries.  Paris intends to damage the facility to force it off-line. 

Janeway asks about the possibility of using phasers to stop him. Tuvok advises against it; it would create a hydrodynamic shock wave throughout The Waters, causing massive damage to the Monean infrastructure and civilian populations. Chakotay suggests using a photon torpedo as a depth charge. Tuvok agrees that this will work. Janeway agrees.

As the Flyer approaches the complex, Tuvok reports the torpedo is ready, but also reports that the Flyer is too far down for it to get close to the craft. Burkus hails again, accusing Janeway of authorizing Paris' action to force the shutdown of the refinery. Janeway responds that an evacuation is advisable, but she intends to protect the facility. Burkus begins to protest further, but she orders the transmission cut. 

Tuvok informs her that Paris would need to come up closer to the surface, away from the blast range, if he intends to fire on the complex. This would put the Flyer within range of the torpedo. Janeway orders Tuvok to fire when this happens. Kim, horrified, asks her if she really intends to fire on Paris. Janeway coldly responds that Paris forfeited his status as a protected member of the crew the second he began this action.

The Flyer begins to rise. Janeway hails it and issues another warning to Paris to stand down. He does not respond. He asks Riga if he is really ready to go through with it. Riga hesitates then nods. Paris arms the torpedo he intends to use.

Janeway issues one final warning to Paris. He does not respond. Tuvok begins counting down the seconds until the Flyer is within range, as Paris counts down the seconds until he launches the torpedo. At the last second, Janeway orders Tuvok to fire. The Flyer fires at the same time as Voyager. Its torpedo streaks toward the complex at the same time Voyagers torpedo races down into the water, toward the Flyer. 

But instead of targeting the Flyer, the torpedo targets its counterpart from the Flyer. The two missiles meet and explode, knocking the Flyer away and disabling it. Inside, Paris and Riga go flying amidst a shower of sparks. Tuvok reports that the Flyer is disabled, but not destroyed. Janeway's is relieved but resolved to deal with Paris for his actions.

Janeway stands in her ready room face to face with Paris. Two security officers are present at the door. Janeway regards Paris sternly. She lists his offenses: insubordination, unauthorized use of a spacecraft, reckless endangerment and conduct unbecoming an officer. She demands to know what he has to say for himself. He resolutely responds that he did what was necessary to save this world; Burkus and the government would never have done what they needed to do.

Janeway responds to Paris that he has disobeyed her direct orders, violated the protocols that govern the crew and almost caused an armed conflict with the Moneans, while understanding his passion and reasoning. But he had no right to take matters into his own hands. She expresses disappointment over his conduct, and that she thought Paris was past this sort of thing after releasing him from prison and giving him a fresh start four years ago. He responds quietly that this time he broke the rules for a good cause. She responds that she admires his principles, but she cannot ignore his actions.

She pronounces his full name and her punishment against him: demotion to the rank of ensign and incarceration for the next thirty days in the brig. Paris stands at full attention, staring straight ahead. Janeway reaches for the two pips on his collar, one black and one gold, indicating his Lieutenant (jg) rank. She plucks the black pip away, leaving only the gold one, the insignia of an ensign. She then orders the security officers to escort the now-ensign Paris to the brig. The officers advance, but Paris shrugs them off, telling him he knows the way. He turns briskly and leaves, the officers behind him. Janeway stares silently at him as the door closes behind them.

Tuvok enters the brig and goes to Paris' cell, rousing and releasing him as his thirty days have been served. Paris steps out, and Tuvok orders him to clean up and report for duty. Paris leaves, the PADD with the letter in his hand.

In his quarters, Paris emerges from his bathroom, shined and shaved, his solitary gold pip on his collar. Lieutenant Torres greets him and invites him for dinner at 0700 (7 in the morning) after his duty shift. She jocularly makes it an order, eliciting a smile from him.

He sits down with the PADD and ends the dictation with a notice that he is out and has returned to duty, and the voicing of a hope that it will allow the elder Paris to better understand him. He then orders the computer to file it and transmit it when Voyager is within range of Earth.

Background information

Production

 The working titles for this episode include "Still Waters" and "Down Deep", with the first completed version drafted .
 The episode's development had a watery starting point. During the fifth season of  or in the hiatus shortly thereafter, script writer and producer Kenneth Biller explained, "Scott Miller brought us this idea a couple of years ago of an ocean in space. Brannon [Braga] and Joe [Menosky] and I fell in love with the image." The writers then attempted to come up with a workable story to feature their oceanic muse. (Cinefantastique, Vol. 31, No. 11, p. 38)
 As the installment's duration at first underran by ten minutes, more plot content was needed for the episode. This turned out to be the subplot that involves Paris enduring confinement and narrating the story. (Cinefantastique, Vol. 31, No. 11, pp. 38 & 52) According to the unauthorized reference book  (p. 273), this subplot was suggested by Paris actor Robert Duncan McNeill, who believed that some of Paris' earlier, rebellious edge needed to be returned to the character. 
 A scene which involved the Delaney sisters at what looks like a formal reception for the Moneans in the Mess Hall appears to have been filmed and deleted from the final episode. A publicity still of the twins, notably dressed in their blue sciences division uniforms, was distributed to the media, and was printed in a feature in .
 Whether or not Robert Duncan McNeill was personally involved in the development of the episode's subplot, he approved of its addition. He remarked, "The first version of that episode I didn't like [....] [We had] an opportunity to look [...] at it and say, 'How can we improve it?' The whole concept of Paris being in the brig from the beginning, and telling this as a flashback in a letter to his father, brought in a whole other element that was much darker and much more interesting. This was more complex; it had a lot of character stuff to play with. All those scenes with Paris in the brig gave it a framework that was much more interesting, and had much more mystery to it. I was very happy with it by the end. I thought it turned into a really good show." (Cinefantastique, Vol. 31, No. 11, p. 52)
 The scenes in which the imprisoned Paris recounts the story for his father were shot after the filming of the episode's other scenes. (Cinefantastique, Vol. 31, No. 11, p. 38)
 For this episode, a shot of the Delta Flyer launching from Voyagers shuttlebay and approaching the water world, while banking to starboard, was reused from the earlier Season 5 outing , simply with a different planet composited into the shot. (Delta Quadrant, p. 273)
 Benjamin Livingston's costume was sold off on the It's A Wrap! sale and auction on eBay.

Continuity 
 The set representing the inside of Captain Proton's rocket ship, as seen here, reused a set of water bubble tubes from the fourth season finale . (Delta Quadrant, p. 274)
 After five years of references, the infamous Delaney sisters appear for the first and only time. They are only seen in holodeck-attire, however a reception scene where both are dressed in sciences division uniforms was filmed and deleted from the episode. Publicity stills for the episode were distributed of both actresses from this scene.
 Because of his actions in this episode, Tom Paris is reduced in rank to ensign. This is the second time in the Star Trek franchise that a main character is demoted in rank; the first occurs in , when James T. Kirk is demoted from admiral to captain. Paris later regains his rank of lieutenant junior grade in the sixth season finale .
 One of the pieces of equipment Riga brings with him was also seen in  as the "auto regeneration unit" Kim warns Janeway off of.
 Reference to 47: the Monean Maritime Sovereignty is made up of 47 regional sovereigns.
 This is the final appearance of Warren Munson as Owen Paris although only his voice was heard during the episode. Richard Herd took over the role, beginning with .

Reception 
 Ken Biller was ultimately dissatisfied with all the efforts the writers made to develop a plot conceptually centered around "an ocean in space." He complained, "Unfortunately, we never quite figured out the best way to tell a story about it." However, Biller thought some of the other aspects of this episode were successful, including the subplot involving Paris' imprisonment. "That ended up being the most interesting thing," he remarked. "I thought the special effects were great and the ocean was intriguing." (Cinefantastique, Vol. 31, No. 11, p. 38)
 This episode was nominated for an Emmy Award for Outstanding Special Visual Effects for a Series. Star Trek nearly swept the category that year. Also nominated were  and . "Dark Frontier" won.
