Anne Hathaway stars in this psychological thriller as Claire Summers, a driven young psychiatrist who consumes herself in work at the expense of her social life. Following a plane crash, Claire is called upon to counsel the few survivors. These men and women are understandably traumatized, showing signs of post traumatic stress syndrome, shock, and in the case of passenger Eric (Patrick Wilson), a state of euphoria. Clair leads a therapy group attended by every passenger except Eric, who will agree to see Claire only on a casual, one-on-one basis on the understanding that he is not a "patient" but a friend. Claire agrees to this reluctantly with the hope that this arrangement will help her reach Eric and get him to open up about his experience. As Claire hears contradictory accounts of the crash from each survivor, she starts to suspect foul play on the part of the airline. Meanwhile, she struggles to keep her ever-growing relationship with Eric professional.
