Killer Klowns From Outer Space - Plot

Plot

In the town of Crescent Cove, California, Farmer Gene Green spies a comet-like object fall to the Earth. Believing it to be Haley's Comet he goes to find it, coming across a large circus tent-like structure he is at first amused by the sight, but he and his dog Pooh Bear are quickly killed by mysterious clown-like creatures. Meanwhile, Mike Tobacco (Cramer) and his girlfriend Debbie Stone (Snyder) had also seen the comet and she convinces him to follow it. Coming across the same structure, they discover a massively complex interior that looks nothing like a circus tent, and a room with cotton candy shaped cocoons. Discovering the old man and a friend's remains in the cocoons, they are nearly captured by the alien clowns who coat them with a popcorn gun as they escape before giving chase with a balloon-animal dog that comes to life. Narrowly escaping, Mike and Debbie travel to the police station to confide in her ex-boyfriend Dave Hanson and his skeptical, curmudgeonly partner Curtis Mooney about the killer klowns from outer space. The latter believes it to be a hoax, and so does Dave after they drop Debbie off at her home and investigate the site to find the ship missing. Coming across a group of cars on the makeout hill "Top of the World" Dave finds the place destroyed and several filled with the cotton candy-like substance and finally believes Mike.

Meanwhile, the Klowns journey into town and proceed to garner a supply of townspeople, using ray guns that resemble toys to wrap them in cocoons. While their tricks seem whimsical and innocent, tricks like boxing gloves and shadow puppets to "rubber mallets" often turn deadly before the townspeople realize what is happening. One Klown invades a drug store knocking over everything in sight and then kills the clerk, while a group of klowns pretend to deliver a pizza to a girls house as a klown jumps out of the box and kills her with his cotton candy ray gun, another klown in the park puts on a puppet show that lures a guy to his death, downtown a little Klown drives up in an alley full of biker thugs, one of the bikers decides to pick on the little klown by smashing his tricycle, the klown gets mad and punches the thugs head clear off while the rest of the gang flees, another klown goes to "Big Top Burger" hut and tries to lure a little girl into its trap but fails (which infuriates the clown), a tall klown (who has the ability to float on the highway) has a demolition derby with a guy on the road, resulting in the klown ramming right into him and plowing him off the road over a ledge to his death.

Mike and Dave encounter Slim, one of the clowns, using a shadow puppet to shrink a crowd of unsuspecting people into the palm of his hand before feeding it to a bag full of baby klowns who look like popcorn, but it escapes before Mike can run him down. Mooney, convinced that the calls to the police station is the result of a hoax encounters one of the clowns and a series of pranks makes Mooney lock him up, he does not realize the threat is real however until it is too late. Dave returns to the station to find two prisoners dead, the station decorated with shoe prints, and Mooney being mimicked like a puppet with Jumbo's hand inserted in his back. Dave shoots Jumbo several times before destroying its nose, which causes it to spin wildly and explode. In town, Mike and his friends Rich and Paul Terenzi, who own an ice cream truck they were using to warn people with notice the town overrun by the Klowns and run to avoid capture. At her home, Debbie is attacked by creatures that grew from the popcorn she had been sprayed with, and then is captured by the Klowns when they arrive, trapping her in a giant balloon. Mike, Dave and the brothers give chase to an old abandoned amusement park where five of the movie's primary clowns (Slim, Fatso, Shorty, Rudy and Bibbo) had already killed a security guard by plastering him with acidic pies.

Journeying through a fun house leading to the ship, the Terenzi brothers become separated, meeting two female clowns who sexually harass them off-screen while Mike and Dave find their way into the ship and free Debbie from her imprisonment after witnessing one of the Klowns using a silly straw to devour one of the liquidized townspeople. They run through the maze of a ship together, encountering several strange traps and tricks along the way before reaching a main room, called "Klown Kathedral" and are surrounded by the Klowns, they are distracted when Rich and Paul arrive after escaping the female clowns in their ice cream truck and manage to trick them into stopping their attack using a fake plastic clown head to give them orders. However a viceroy and supposedly the giant leader of the Klown army, named Jojo the Klownzilla, arrives as a stringed puppet and breaks free from the strings, wanting to destroy the humans himself after the other Klowns flees from the leader, he destroys the truck with Rich and Paul still inside. Dave starts a battle with Jojo, called Klownfrontation, Dave shoots at the massive clown to distract him from Debbie and Mike's escape. They escape as the ship begins to coil in and spin like a top before lifting off the ground to leave earth. Inside, Dave destroys the massive clown's nose with his badge and as a result he explodes and the ship is destroyed with him. Having escaped to the authorities who had gathered outside the amusement park, Mike and Debbie briefly mourn their friends' loss until the Klown's miniature car drops out of the sky. Dave is alive and they all embrace before Paul and Rich appear from the back of the car themselves, having hidden in the ice cream coolers to avoid the explosion.
