House of 9

Nine strangers wake up in a house with no recollection of how they got there and no way out. A voice on the PA introduces them to the grisly game they've been chosen to play. Last man standing wins $5 million in cash and their life back. When all attempts to break out together fail, tension turns to violence and violence to death and suddenly it's every man for himself as they fight for their lives. Why are they here? Who will survive? And what will it cost them in the end? (official distributor synopsis)
