Chris (Joseph Gordon-Levitt) used to be a dazzling boy: as an ice hockey star, he had a superior family background, a beautiful girlfriend, and his life was as smooth as a flat road. A car accident destroyed everything. He suffered from short-term amnesia and spent every day in an uncontrollable state. Even small problems such as where to put the car keys, Chris could not remember with certainty. Now he has become a janitor at the bank, and his only friend around is the blind Louis (Jeff Daniels), who guides Chris with a happy outlook on life. Someone tries to get close to Chris, that is Gary (Matthew Goode). Gary is very concerned about Chris's situation, introduces him to a girlfriend, awakens his inner desire to restore his previous life, and more importantly, conspires with him to participate in a bank robbery. Chris not only faces the distress of amnesia, but now has to deal with this tricky plan to take control of his life back into his own hands.
