A ferry filled with crewmen from the USS Nimitz and their families was blown up in New Orleans on Mardi Gras. BATF Doug Carlin is brought in to assist in the massive investigation, and gets attached to an experimental FBI surveillance unit, one that uses spacefolding technology to directly look back a little over four days into the past. While tracking down the bomber, Carlin gets an idea in his head: could they use the device to actually travel back in time and not only prevent the bombing but also the murder of a local woman whose truck was used in the bombing? Written by Jeff Cross

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.
