Casey is an adolescent boy whose life is constantly influenced by his intense fear of clowns. His two older brothers, Geoffrey and Randy, are mostly disobliging. One night, the three boys are left alone so they decide to visit a local circus, despite Casey's uncontrollable coulrophobia. While at the circus, Casey innocently visits a fortune teller and she reveals to him that his life line has been cut short. Meanwhile, three psychotic mental patients, who have escaped an insane asylum, murder three clowns and steal their identities of Cheezo, Bippo, and Dippo by taking their makeup and costumes.
