House of 9

“Nine Strangers. One House. Only One Will Get Out... Alive.”

Nine strangers wake inside a locked house with no memory of how they arrived and no door that opens. A voice on the PA calls itself the Watcher and explains the terms: the last one alive walks out with $5 million. Steven R. Monroe frames it through hidden surveillance cameras, and Lea (Kelly Brook) is left trying to read the others as the group splits.
