House of 9

Nine unconnected strangers awaken as captives in a sealed mansion. A disembodied voice known as The Watcher explains they are part of a sick game for his entertainment. The prize is five million dollars, but the price of winning is being the sole survivor. As paranoia and desperation set in, their initial attempts to cooperate crumble. Alliances shift and friendships dissolve, leading to a brutal, violent battle for survival where everyone is both a potential victim and a killer.
