You were on your way to a summer camp holiday, anticipating a great holiday. But instead you’ve been locked up in an abandoned school that turns out to be home to an evil monster. He used to be a good nun, but she’s fallen under the influence of the devil and has become a demon. Now it preys on all living things and tries to kill anyone who enters the school grounds. Stay alive for five days and then you can get out of this place alive. Try not to let the nun see you.
