In common with all the previous Simpsons Halloween episodes, the program is made up of three self-contained stories; "The Homega Man", "Fly vs. Fly" and "Easy-Bake Coven". In "The Homega Man", Homer Simpson appears at first to be the only person left alive on Earth. He then discovers that other people have survived but have been mutated. The segment is based on the 1971 movie The Omega Man. The aliens Kang and Kodos make a brief appearance in the story. In "Fly vs. Fly", Bart Simpson's head gets transferred to the body of a fly and the fly's head is placed on Bart's body. The segment parodies the 1958 movie The Fly. In "Easy-Bake Coven", a 17th-century version of Marge Simpson is accused of witchcraft. The segment spoofs the 1996 movie version of Arthur Miller's The Crucible.
