This slapstick parody of space movies chronicles the riotous exploits of a group of dim-bulbed, misguided aliens under the mistaken impression that they are supposed to invade the Earth after they hear a rebroadcast of Orson Welles' notorious "War of the Worlds" one Halloween night. Thinking they are late, they rush in with their ramshackle spaceship and end up in Big Bean, Illinois, a peaceful midwestern town. Naturally after they announce they want to kill the "Earth scum," the residents want to kill them. Fortunately, the town sheriff and his daughter try to keep the moronic Martians safe and help their captain get them safely back in space.
