Four interwoven stories that occur on Halloween: an everyday high school principal has a secret life as a serial killer; a college virgin might have just met the one guy for her; a group of teenagers pull a mean prank, and a bitter old recluse receives an uninvited guest.

A small town is taken over by an alien plague, turning residents into zombies and all forms of mutant monsters.

High school senior Wendy's premonition of a deadly rollercoaster ride saves her life and a lucky few, but not from death itself — which seeks out those who escaped their fate.

A masked villain wreaks mayhem on the city of Coolsville with a monster machine that creates real-life versions of Mystery Inc.'s former foes like The 10,000 Volt Ghost, The Cotton Candy Glob, The Skelemen and The Pterodactyl Ghost. Fred, Daphne, Shaggy, Velma and Scooby-Doo launch an investigation into the monster outbreak that leaves Shaggy and Scooby questioning their roles in Mystery Inc. Eager to prove their detective skills, the ever-ravenous duo comes up with a secret plan to solve the mystery all by themselves. Can the gang unravel their most challenging case?
