Déjà Vu

On Mardi Gras morning, a ferry carrying sailors and their families explodes on the Mississippi River near New Orleans, killing 543 people. The disaster triggers the federal investigation into a suspected domestic terrorist attack. Rescue attempts and frantic reports flood the scene as investigators begin to unravel what happened.

ATF Special Agent Doug Carlin discovers signs that a bomb was planted and analyzes the ferries’ explosion aftermath. He learns that Claire Kuchever had called his office on the morning of the bombing, hinting at an abduction prior to the blast. The case begins to connect Claire to the killer and the motive behind the attack.

Doug informs Claire's father of the grim findings and conducts a meticulous search of Claire's apartment. Clues reveal that she was abducted and killed hours before the explosion. The team grows more convinced that the tragedy involved a deliberate premeditated act.

FBI Agent Paul Pryzwarra initiates a new unit led by Dr. Alexander Denny, leveraging a surveillance program called Snow White. The program claims to reconstruct events from the past using satellite footage. The team hopes to link the ferry bombing to Claire and the suspected bomber.

Doug studies Claire's past footage within Snow White and identifies the bomber from a call about a truck she has for sale. He uses this information to map the suspect's movements and prepare for a confrontation. Claire’s life becomes the crucial key to tracing the killer.

Doug deduces that Snow White is actually a time window and convinces the team to send a note to his past self with the suspect's time and place. Larry Minuti retrieves the note but is shot while attempting to arrest the suspect. The timeline crossing marks the first major breach of cause and effect.

Using a mobile Snow White unit, Doug follows the suspect's past movements to his hideout, where the wounded Minuti confronts the killer. He witnesses Minuti's murder through the time window, pulling him deeper into the dangerous chase across timelines. The danger escalates as the killer remains at large.

In the present, facial recognition identifies the bomber as Carroll Oerstadt, a volatile patriot rejected from military service. He confesses to killing Minuti and Claire, and he disposes of Claire's truck to transport the bomb, staging her death as a ferry victim. The government closes the case, yet Doug remains determined to alter events.

Doug urges Dr. Denny to use Snow White to send him back to the morning of the bombing to save Claire. He argues that altering history is the only way to prevent the tragedy and the deaths that followed. The team weighs the ethical implications, but Doug is resolute.

Doug is transported back to the morning and wakes in a hospital emergency room, where doctors manage to revive him. He then steals an ambulance to reach the bomber's hideout before the explosion, highlighting the extreme risks involved in changing history.

Doug arrives at the hideout in time to intervene, but Oerstadt shoots him and Claire is captured. He regains enough strength to assist in the plan to save Claire, and the past collides with the present in a tense struggle. The rescue attempt hangs in a delicate balance.

Doug escorts Claire to her apartment to tend to his wound, but she remains wary and demands proof of his identity. He convinces her by recounting details only the present Doug would know, and they resolve to face the danger together. A shift from suspicion to trust marks their alliance.

Doug and Claire head toward the ferry dock, where Doug aims to disarm the bomb in Claire's truck. Oerstadt realizes he’s being followed, captures Claire and ties her to the steering wheel, sparking a deadly gunfight aboard the water. The showdown pushes toward a fatal outcome.

In a climactic struggle, Doug distracts Oerstadt using information from his future interrogation, and Claire rams the truck into Oerstadt, killing him. Doug dies in the underwater explosion as they drive the vehicle into the river to save the ferry passengers. Claire survives the ordeal and is approached by a future Doug on the pier.

Picked up by a rescue boat, Claire is approached on the pier by the Doug Carlin from her present timeline. The encounter confirms the odd mercy of time travel, leaving her to ponder a life lived with foreknowledge of the future. The ending blends tragedy with a fragile, bittersweet hope.
