As good friends gather together to welcome in the New Year, a suicidal psychopath bursts in the front door and invades the party at gunpoint. He executes his "game" of death by igniting a ritual of torture and murder. The intruder is driven by a hidden agenda to force them to confess their sins and divulge secrets they have tried to hide from each other their whole lives. Their only hope is one lone person who has gone upstairs and is, so far, undetected by the intruder. But does their friend get to help and rescue them? Or is something challenging him to do the unexpected? Not for the faint-of-heart!
