When Molly Heyworth comes across an eerie video on the internet, she believes it to be a hoax. It’s an early instalment to a video blog detailing the Garrison family’s home renovations. On her computer, Molly watches the couple tearing down a wall to reveal a room, where no room should exist. But what unnerves her is the strange altar the Garrisons find inside, where strange symbols on the walls and remnants of blood hint at Satanic rituals.
