Simon (Stephen Gately) is a theology student who persuades his friends to prove the existence of evil by summoning a demon. By dawn the next day, all but one are dead. Six years later, Alice (Myanna Buring) and her friends, including Jock (Clayton Watson), are looking for a roof over their heads after they are evicted from their student digs. When they break into the old theology college, they disturb a source of evil that plays on human frailty by exposing each of their darkest secrets. Over one terror-filled weekend, the friends are forced to re-evaluate their beliefs as they become trapped inside the abandoned building by an entity too impossible to believe, yet is hell-bent on their destruction.
