Twelve housemates enter a house as part of a bold, new television show. All they know is they're to have their actions monitored 24 hours a day and compete in a series of tasks with the knowledge that - at the end of the show - one of them will walk away with 100,000 pounds. But all is not as it seems, and the truth - and danger - becomes apparent as soon as the doors lock them in on their first night, and the first of the 12 is murdered....

With no way out and The Controller instructing them to kill each other until only one stands - the housemates have no choice but to play the game in Matt Shaw's new psychological horror.

Who will be victorious?
