The film opens with a car crash on the Brooklyn Bridge, and introduces Henry Letham (Ryan Gosling), a survivor of the crash, sitting, unharmed, next to a burning car on the bridge. Psychiatrist Sam Foster (Ewan McGregor) and his girlfriend (and former patient), art teacher Lila (Naomi Watts) are then introduced in a new scene. Sam discusses his patient, Henry, a college student and aspiring artist whom he describes as depressed and paranoid, with feelings of guilt and remorse over having 'set fire to' his car at the beginning of the film. Henry mentions that he sometimes hears voices, and seems able to predict future events. Henry is also suspicious of Sam because he had suddenly been called to stand in for his ordinary psychiatrist, Beth Levy (Janeane Garofalo). Henry has told Sam of his plans to kill himself that Saturday at midnight, which Sam finds very troubling. Lila, who has survived a past suicide attempt, offers to help to dissuade Henry from killing himself. Read more on Wikipedia.
