After a plane crash, a young therapist, Claire, is assigned by her mentor to counsel the flight's five survivors. When they share their recollections of the incident -- which some say include an explosion that the airline claims never happened -- Claire is intrigued by Eric, the most secretive of the passengers. Just as Claire's professional relationship with Eric -- despite her better judgment -- blossoms into a romance, the survivors begin to disappear mysteriously, one by one. Claire suspects that Eric may hold all the answers and becomes determined to uncover the truth, no matter the consequences.
