Saturday Morning Mystery (2012)

A dark and bloody parody about a Scooby-Doo-like team of paranormal investigators and their devoted dog. With the crew nearing bankruptcy, they're hired to get to the bottom of a series of spooky events at the remote Kyser mansion, an old religious school plagued by rumors of satanism and ritualistic murder. They're experts at debunking ghost stories, so they get right to work, and despite the ominous signs that this isn't just another greedy land-developer or bitter landlord, they set up to stay the night. When the sun goes down, the truth comes out: this place might actually be haunted...by sadistic spirits or something much, much deadlier.
