A group of martians pick up a radio clip from "War of the Worlds" mistaking it as a radio transmission they land in a small Illinois town and try to take over but it's Halloween and everyone thinks the martians are trick-or-treaters. Only a few of the young kids realize they're trying to destroy earth, but when they learn that the aliens don't mean any harm they try to help them escape from earth, plus the ship may destroy the earth if they do not leave in time.
