A dedicated psychiatrist struggles to keep his grip on reality when he embarks on a nightmarish chase through the streets of New York to find an emotionally disturbed student, who has confided in him his single-minded determination to commit suicide. Marc Foster's psychological thriller, starring Ewan McGregor, Ryan Gosling, Naomi Watts and Janeane Garofalo.

Psychiatrist Sam Foster has a new patient, Henry Letham, who claims to be suicidal. In trying to diagnose him, Sam visits Henry's prior therapist and also finds Henry's mother -- even though Henry has said that he murdered both of his parents. As reality starts to contradict fact, Sam spirals into an unstable mental state. Then he finds a clue as to how and when Henry may try to kill himself, and races to try to stop him.
