US army combat psychiatrist David Mc Namara has been hit hard since retiring from active duty: struggling with mysterious choleric attacks and a marriage in crisis, he is now called to New York for his expertise in forensic psychiatry. At the Staten Island Forensic Hospital he is to attend to five young men and women, who were found screaming, scared, with no memory or orientation across New York City. Dave begins to cautiously explore the memories of his young patients – and makes alarming discoveries.
Players not only take over the role of Dave McNamara, who investigates in the present, but also will take control of the five patients in flashbacks. The memories that McNamara brings to light are explored by the player in backward chronological order – the further players progress in the game, the further back in time he advances.
