How far would you be willing to go to reclaim your life when your identity is stolen? Liam Neeson takes action as Dr. Martin Harris, a man whose life becomes unglued after he wakes up from a dramatic car accident while on business with his wife (January Jones) in Berlin. Dazed to discover that his wife does not recognize him and his identity has been appropriated by another doctor (Aiden Quinn), Harris teams up with a reluctant immigrant (Diane Kruger) to help him solve the mystery.
