The film was released on April 3, 1998. It received mostly negative reviews and grossed $93 million at the box office.

Plot
A nine-year-old boy with autism, Simon Lynch, is given a sophisticated puzzle book by his teacher. Simon quickly solves a particular puzzle and phones a number encoded in the solution. This call reaches two National Security Agency cryptographers, Dean Crandell and Leo Pedranski, who created the new cypher Simon has cracked. Pedranski and Crandell report the situation to their boss, Lieutenant Colonel Nick Kudrow, who severely rebukes the pair for their unauthorized actions, describing Simon and his abilities as a national security threat. Two assassins, Peter Burrell and Shayes, are sent by Kudrow to terminate the boy and his parents, Martin and Jenny. Posing as a police detective, Burrell murders both Simon's mother and father, but is unable to find Simon.
FBI agent Art Jeffries, who was recently demoted to a desk job after an unsuccessful negotiation during a bank robbery hostage situation, is sent to investigate and finds Simon in a hidden crawl space in his bedroom closet. Simon is taken to a protection ward at the hospital, where a nurse explains to Art about Simon's autism. Burrell impersonates a doctor and makes another attempt on Simon's life. Art saves Simon and flees the premises, and tries unsuccessfully to convince Simon that he is a friend instead of a stranger. Later, while on a train, Burrell’s partner, Shayes, tries to kill Simon, but Art intervenes, knocking him off the train and onto the tracks as another locomotive passes, killing him.
Under Kudrow's direction, the NSA frames Art as Simon's kidnapper. However, fellow agent and friend Tommy Jordan does not believe the story and assists Art, who borrows Jordan's car and takes Simon back to his house. Simon again calls the telephone number written into the code and Art is able to talk to Crandell and Pedranski. As Crandell arranges a meeting at the Wrigley Building by the next morning, Art goes to the meeting, leaving Simon under the care of a woman in a coffee shop, Stacey Siebring, who later agrees to help Art take care of Simon. Crandell tells Jeffries about Mercury and Kudrow, but is shot dead by Burrell before he can reveal everything. Pedranski, having learned Crandell's fate, tries to reveal Kudrow's unlawful actions by writing letters on a typewriter: one to Art and a carbon copy for the Senate Oversight Committee, but Burrell tracks Pedranski down and kills him as well, confiscating the letters. However, the assassin overlooks Pedranski's carbon copies, which his girlfriend, NSA analyst Emily Lang, takes to the FBI. Jordan discreetly arranges for her to meet with Art to show them the carbon copies; covered in Pedranski’s fingerprints, they become crucial evidence. Art then goes to Kudrow’s home during his birthday party, and demands that Kudrow announce on national TV that the Mercury Encryption Project is a failure.
Under Art's suggestion, Jordan arranges for Simon to go into the Witness Protection Program, but Kudrow, unwilling to reveal his failure and determined to kill Simon, forcibly takes charge of the Witness Protection while revealing to Lomax, the FBI Special Agent in charge, that Jordan forged the witness protection documents. However, unknown to Kudrow, Tommy shows the carbon paper evidence to Lomax and confirms that the fingerprint markings on it were Pedranski's, validating the evidence against Kudrow. Stacey and Simon leave for the pick-up point at the top of a skyscraper, where Kudrow and Burrell prepare to take Simon away on a helicopter, but Jeffries, with Jordan and an FBI task force's help, sets a trap at the meeting spot. A gunfight ensues between Burrell and the FBI, ending with Burrell being fatally slashed by glass shards when plexiglass windows are blown inward, while Art fights Kudrow one-on-one, and Simon assists him by retrieving his gun. Kudrow attempts to throw Simon off the roof, but Jeffries shoots him multiple times, and he falls off the edge and to his death.
Art and Siebring later visit Simon, now living with foster parents, at his school. Simon embraces Art as a welcome friend, having accepted him as a person he trusts.

Critical response
On Rotten Tomatoes the film has a score of 21% based on reviews from 57 critics with an average rating of 4.37/10. The consensus states: "Mercury Rising lays the action on thick, but can never find a dramatic pulse to keep viewers -- or Bruce Willis -- engaged with its maudlin story." Audiences polled by CinemaScore gave the film an average grade of "B" on an A+ to F scale.Roger Ebert gave the film two stars out of four, writing: "Mercury Rising is about the most sophisticated cryptographic system known to man, and about characters considerably denser than anyone in the audience. Sitting in the dark, our minds idly playing with the plot, we figure out what they should do, how they should do it, and why they should do it, while the characters on the screen strain helplessly against the requirements of the formula." James Berardinelli rated it one and a half out of four stars, saying: "The script for Mercury Rising is exceptionally tiresome and hard-to-swallow. ... Once again, certain standby plot elements -- the high-level government conspiracy and the maverick law enforcement agent -- are recycled, and not to good effect. While Bruce Willis can play the action hero as well as anyone in Hollywood, this particular outing leaves him marooned in situations that are characterized by too little tension and too much nonsense."

Bruce Willis received the 1999 Golden Raspberry Award as Worst Actor for his performance (as well as for Armageddon and The Siege).
