House of 9

Nine strangers wake up in a mysterious house with no recollection of how they got there, only to be introduced to a deadly game where the last person alive wins $5 million. As they try to escape, the group's efforts are thwarted, and they turn on each other in a desperate bid for survival. Lea, played by Kelly Brook, is one of the survivors who eventually emerges from the game, only to discover that the true horror has only just begun.
