As the film reaches its climax, ATF agent Doug Carlin (played by Denzel Washington) has been investigating a terrorist bombing in New Orleans. Through the use of a top-secret government program that allows him to view past events, Doug discovers that the bomber, Carroll Oerstadt (played by Jim Caviezel), has been targeting the city to avenge the death of his wife.
In a race against time, Doug utilizes the program to track down Carroll and prevent a catastrophic attack on a ferry carrying hundreds of innocent people. With the help of Claire Kuchever (played by Paula Patton), a technician involved in the program, Doug gathers crucial evidence and pieces together the puzzle of Carroll’s plans.
In the final act, Doug confronts Carroll on the ferry just as he is about to detonate the bomb. A tense standoff ensues, with Doug desperately trying to convince Carroll to stand down and spare the lives of the passengers.
In a dramatic turn of events, Doug manages to disarm the bomb and apprehend Carroll, saving the ferry from destruction. However, during the struggle, Carroll is fatally wounded.
As the dust settles, Doug reflects on the events that have transpired and the sacrifices made in the name of justice. Despite the challenges and complexities of the case, he finds closure and a sense of peace.
The film ends with Doug bidding farewell to Claire, who is unaware of their past interactions due to the altered timeline created by the government program. Doug looks to the future with hope, knowing that he has prevented a tragedy and made a difference in the world.
Overall, the ending of “Deja Vu” combines intense action with thought-provoking themes about time, fate, and the power of human determination. It provides a satisfying conclusion to the thrilling journey of its characters.
