When a new geothermal heating system is installed under the high school, it thaws out a Neanderthal ancestor of Jughead!

It all starts the day the local TV station plays a twelve-hour monster movie marathon, followed by a trivia contest. Archie should have known something was wrong when Jughead actually wins! It turns out, the TV station has been invaded by a body-snatching space spud. When the bad guys are supernatural, all bets are off. Archie faces his greatest challenge yet when Riverdale is invaded by a gang of hungry vampires. Things come to a chilling climax at Veronica's Halloween party as Reggie, Betty, Jughead and Archie are turned into vampires, one by one, until only Veronica is left to save the world! But can she do it without messing up her hairdo or breaking a nail...? A feature-length compilation of the episodes Attack of the Killer Spuds, Scarlet Night, I Was a Teenage Vampire, and Halloween of Horror.
