Determined to escape her abusive mother and save her younger sister from the dead-end existence that seems inevitable for them both, Rocky (Jane Levy) will do whatever it takes to get away. She and friends Alex (Dylan Minnette) and Money (Daniel Zovatto) have pulled off a series of elaborately planned burglaries in order to come up with enough cash to escape their dire Detroit hometown. Their petty crimes have netted meager rewards, however, so when the trio learns that a blind man (Stephen Lang) living in an abandoned neighbourhood has a small fortune stashed in his house, they agree to go for their biggest and final heist. But their plan goes dangerously wrong when their intended victim turns out to be more frightening than they ever anticipated. As he stalks them relentlessly through his heavily fortified house, they are horrified to discover that he has more than just money hidden away.
