A group of young men dare a classmate to reach the porch of a legendary old house, said to be haunted by the thirteen victims of a family massacre. In hopes of making a viral video they arm him with a video camera to prove he was there or to capture him fleeing in terror before even reaching the house, as others have. When he doesn't return, the guys must go in to get him. Inside they discover the truth about the house, the fate of their friend and their own fate as well.
