Teenage Exorcist

Tired horror spoof finds the prim Diane (Stevens) renting a creepy house from an equally creepy real estate agent (Berryman). After she moves in, Diane begins having horrible nightmares and calls her family for help. When they arrive Diane has turned into a chainsaw-wielding seductress. The family is so distressed that they misdial the phone and wind up with a pizza delivery geek (Deezen) instead of the exorcist they need.
