He finds himself unquestioningly accepting Max's plea for help and the brothers swap places in order for Max to take care of some business. All he claims to need is a couple of days in the outside world to settle his debt. But soon Daniel realizes Max isn't coming back, and that the clinic is far from a place of recovery. Struggling to get anyone to believe who he really is, Daniel finds himself trapped in a cruel and highly secretive prison: this is no sanctuary, it's a living nightmare . . .
