In order to create a viral video, they armed him with cameras to prove that he was there or, like others, captured footage of him fleeing in terror before he arrived at the house. When he doesn't come back, the guys must go in and catch him. Inside, they discovered the truth about the house, the fate of their friends, and their own destiny.
