Story background.
"Deep Space Nine" tells the story of a space station near the planet Bajor administered by the United Federation of Planets as the Bajorans recover from a brutal decades-long occupation by the aggressive Cardassians. The station guards a wormhole leading to the distant Gamma Quadrant, home of an expansionist empire known as the Dominion, which is ruled by the shapeshifting Changelings. This episode is part of the Dominion War plot arc, in which the Dominion allies with Cardassia and wages war against the Federation and their allies.
This episode is the conclusion of a six-episode story that spans the start of the sixth season. At the end of the previous season, the Dominion captured the titular space station, but the Federation blocked the wormhole with a minefield to prevent reinforcements from arriving from the Gamma Quadrant. Over the following episodes, DS9's Starfleet crew, led by Captain Benjamin Sisko, continue the war against the Dominion on the starship "USS Defiant"; the main characters remaining on the station, led by Major Kira Nerys, work to undermine Dominion rule; Dominion representative Weyoun and Cardassian leader Dukat attempt to dismantle the minefield; and DS9 security chief Odo, a rogue Changeling, receives a visit from another Changeling hoping to persuade him to return to his people. By this point, the technician Rom has been arrested by the Dominion authorities for attempting to prevent destruction of the minefield; and Sisko is leading a Federation fleet aimed at retaking DS9 for the Federation before the minefield comes down.
Plot.
With eight hours before the minefield is destroyed, Sisko's fleet engages the Dominion fleet defending DS9. Sisko orders Federation fighters to engage the Cardassian warships, hoping the less disciplined Cardassians will break formation and create a hole in the Dominion lines. Aboard DS9, Dukat sees through Sisko's ruse; he deliberately allows some of his ships to open a hole in the formation to set a trap for the Federation fleet. Aware that Dukat is setting a trap, Sisko nonetheless orders his ships forward, desperate to reach the station.
Meanwhile, Dukat's aide Damar arrests Kira, Sisko's son Jake, and Rom's wife Leeta, correctly surmising they are part of a conspiracy against Dominion rule. The visiting Changeling, attempting to break Odo's bond with the "solids" and return him to his own people, tells Odo of Kira's arrest.
As the Federation fleet becomes overwhelmed, a Klingon fleet arrives and flanks the Dominion. They clear a path for the "Defiant", though the rest of the allied ships are unable to follow.
Rom's brother Quark and Dukat's daughter Ziyal free Jake, Kira, Rom, and Leeta from jail. Kira and Rom set off to sabotage the station's weapons. They are cornered by Dominion soldiers, but are rescued by Odo and his security team. Rom disables the weapons, but seconds too late to prevent the destruction of the minefield.
Sisko orders the "Defiant" into the wormhole, where they encounter a massive Dominion fleet. As Sisko prepares for a desperate suicide mission, he receives a vision from the Bajoran Prophets, the powerful aliens who live in the wormhole, who are upset that he intends to sacrifice himself before fulfilling their purposes. Sisko pleads with them to help the Bajorans, who created a religion around them. The Prophets cause the Dominion ships to vanish, but warn Sisko that a penance will be exacted.
The "Defiant" exits the wormhole and fires on the station, which cannot respond due to Rom's sabotage. Meanwhile, the Klingons and the Federation have outflanked the Dominion fleet, with 200 ships heading for Deep Space Nine. The Dominion evacuates, but Ziyal refuses to leave, confessing to her father that she helped Kira and her friends escape. Damar overhears her confession and shoots her as an enemy of the state. Dukat collapses in grief as she dies in his arms.
By the time Sisko arrives on the station, Dukat is in a holding cell, sobbing over the loss of his daughter. As he is escorted to the infirmary, he returns Captain Sisko's baseball.
