Plot

Just outside the Californian town of Crescent Cove, Mike Tobacco and his girlfriend Debbie Stone are spending time at the local lovers' lane when they witness the arrival of a strange glowing object. Nearby, a farmer, perceiving it as Halley's Comet, ventures into the woods to find the impact site. He stumbles upon a circus tent-like structure, during which he is captured by clown-like extraterrestrials known as "Klowns". Arriving to investigate for themselves, Mike and Debbie enter the structure and discover a complex interior with bizarre rooms, eventually realizing that it is the object and a spaceship. They find the now-fleshless farmer encased in a cocoon made out of a cotton candy-like substance and are discovered by a Klown, which shoots popcorn at them from a bazooka-like weapon and then pursues them.
