On Fat Tuesday, Mardi Gras in New Orleans, a ferry (the “Sen. Alvin T. Stumpf”) is carrying several hundred U.S. Navy sailors and their families from the Algiers dock to a celebration, when it explodes and sinks into the river, killing at least 543 on board. Agent Doug Carlin (Denzel Washington) from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is sent to investigate the explosion and discovers evidence that the attack was by a domestic terrorist. He meets with the investigating police officers and FBI Agent Paul Pryzwarra (Val Kilmer), letting them know of his findings. Back at his office, Doug learns about a charred body pulled from the river, that of a Claire Kuchever (Paula Patton). However, unlike the other bodies found in the river, this one was discovered before the explosion.
After Pryzwarra is impressed with Doug’s detective expertise, he convinces him to join a newly formed government-funded detective unit whose first case is to investigate the explosion. With a team led by scientist Dr. Alexander Denny (Adam Goldberg), they investigate the events leading up to the explosion by using a new program called “Snow White”, which enables them to look into the past (4 days, 6 hours, 3 minutes, 45 seconds) in detail. The catch is, they can only see the events once – there is no fast forwarding or rewinding, although they can record what they see. Convinced that Claire is a vital link to the case, Doug persuades the team to focus on her. Sure enough, while investigating Claire’s past through “Snow White”, eventually the bomber calls her to try and purchase her car to use to blow up the ferry. Although he decides to not purchase her car, during the phone call, the “Snow White” team is able to discover an exact time and place where they know the terrorist will be.
After tending to a bullet wound at Claire’s house, Doug goes to the ferry where, with Claire’s help, he kills Carroll, but is unable to disarm the bomb. To save everyone on the ferry, Doug has Claire drive the SUV with the bomb off the ferry into the water just before it explodes. Claire is able to escape, but Doug is unable to get out before the bomb explodes and dies in the underwater explosion. As Claire mourns Doug’s death, she is approached by another Doug Carlin, the one from the present, who consoles her. As they drive off, the Beach Boys’ song, “Don’t Worry Baby”, which had played at the beginning of the film, plays on the radio.
