Stan Helsing (Steve Howey (actor)) is an underachieving employee at a video rental store named Schlockbuster whose personal mottos are "Don't get involved" and "Don't talk about it". His teen-aged boss Sully orders him to drop off a bag of movies to the mother of the store's owner or risk not having a job Monday morning. Despite his arguments, he agrees to the request and manages to get his friend Teddy (Kenan Thompson), his ex-girlfriend Nadine (Diora Baird) and ditsy blond massage therapist Mia (Desi Lydic) to take him there before they attend a Halloween party, even though it is on the other side of town.
