Deja Vu (2006)

In Algiers, New Orleans, after the explosion of a ferry transporting the sailors from the USS Nimitz and their families with 543 casualties, the lonely AFT agent Doug Carlin is assigned to investigate the terrorist attack. Without any lead, he is informed by Sheriff Reed about a corpse of a woman that was found one hour before the explosion, but burnt with the same explosive. He is invited by FBI Agent Pryzwarra to join the surveillance team leaded by Jack McCready in the investigations, using a time window and Einstein-Rosen bridge through seven satellites to look back four and half days in time. He discloses the identity of the mysterious dead woman called Claire Kuchever and decides to follow her last moments trying to find the criminal. Along the surveillance, Doug falls in love for Claire and tries to change destiny, saving her life.
After an explosion on a ferry kills over 500 people including a large group of party-going sailors, an ATF agent investigates the crime. AN FBI agent also joins the investigation. Impressed with the ATF agent's skills, the FBI agent invites him to join a new team that has a new program that uses satellite technology to look backwards in time for 4-1/2 days to try to capture the terrorist. Meanwhile a young woman who was burned washes up on shore. Meant to look like part of of the explosion, the body arrives at its location too soon, which leads the agents to believe her death is related to the explosion. As they use the new technology to study the woman, the ATF agent determines that this is not satellite imagery but somehow is using a time warp. From this point in the film, the movie moves from a crime film to a sci-fi time paradox film. Nonetheless, the action is non-stop and always captivating. The end of the film may be confusing to some people, but it is all laid out if one cares to look carefully. Contains some extreme violence that some may find disturbing, particularly during the explosion when many people are shown jumping off the boat in flames.

When a bomb explodes on a ferry boat in New Orleans, special operatives from the FBI and ATF come to the scene, including ATF agent Doug Carlin. After viewing satellite surveillance, Carlin also stumbles upon a woman named Claire Kuchever, who has been murdered shortly before the Ferry incident. Carlin also finds out that he can use the surveillance systems to travel backwards in time. So, he time warps 4 days before the Ferry incident, so he can stop Claire's murder, and to stop the Ferry incident.
