An explosion on a ferry caused more than 500 deaths, including a large group of sailors who attended the party. An ATF agent investigated the crime. An FBI agent also joined the investigation. Impressed by the skills of the ATF agents, the FBI agents invited him to join a new team. With a new plan that uses satellite technology to look back 41/2 days and try to catch terrorists. At the same time, a young woman with burns was dragged ashore. To appear to be part of the blast, the body arrived at its location prematurely, leading officers to believe that his death was related to the blast. When they used the new technology to study the woman, ATF agents determined that it was not a satellite image, but used a time warp in some way.
