When a New Orleans ferry carrying 500 passengers is destroyed by a bomb, Doug Carling; a newly-recruited FBI agent is drafted in to track down the perpetrator. When a body is found floating in the river, it is determined that the victim was murdered before the ferry blast occurred. Unfortunately, the victim was the impossibly beautiful Claire Kuchever (Paula Patton), whose death has begun to torment Carlin. Adding a new level to the investigation is a top-secret FBI invention, which allows a select group to view the past on screen as if it had been videotaped days earlier. The more Carlin sees of Kuchever, the more connected to her he becomes, until he decides to risk his life by travelling back in time and altering the course of history.
