The first of the annual Halloween spook-fest. In 'Bad Dream House', the family move into an old haunted house, and are possessed to kill each other. In 'Hungry are the Damned', the family are abducted by Kang and Kodos, and fattened up to the extent that Lisa questions their motive. Her nosiness ends up in the Simpsons being dropped off home again. In 'The Raven', a poem by Edgar Allan Poe is recited with the family as the characters.
In a parody of the original Frankenstein film, Marge warns viewers that the following program (The Simpsons) may give their children nightmares, so she suggests the adults to "tuck your children into bed tonight instead of writing us angry letters tomorrow." However, the viewers ignore her and let their children watch it anyway.
When Homer comes back from trick-or-treating, he notices Bart and Lisa are telling ghost stories. He climbs up and eavesdrops while Bart comments on Lisa's first story. Bart starts telling his own story called:
The Simpsons move into a new home at a great price. Lisa and Marge are scared there is an evil presence lurking in the house, though Homer says there's nothing to worry about despite there being a vortex in the kitchen, Homer throws in an orange into the vortex then the ones who live in the world throw it out with a note that asks them not to throw in stuff. Bart being strangled by lamp cord, the house threatening the family to leave, and being thrown up to the ceiling. When everyone tries to settle in to sleep, the house brainwashes everybody to kill each other. When they stop what they're doing, thanks to Marge not being brainwashed, the house threatens that they will die horribly. Marge ends up angrily telling the house to shut up, and after a few moments, it complies. Marge then explains that since they are living in the house, the house is going to have to accept this. The house asks them to leave for a moment as it decides what to do. It determines it would rather die than live with the Simpsons, and the house implodes into nothingness.
The Simpsons are having a barbecue until an alien ship abducts them. When they arrive on the ship, they meet Kang, Kodos, an unnamed alien and Serak the preparer, who treat the Simpsons extremely well by giving them countless amounts of food to hold them over until the great feast at Rigel 4. Lisa becomes suspicious and thus, one night, wanders around the ship & heads into the kitchen when Serak leaves. She mistakes the book "How To Cook For Forty Humans" as "How To Cook Humans" and accuses the Rigelians. They are angered at the Simpsons and they are sent back home to live the life of not gods, but normal human beings. Lisa then speculates that they, the Simpson Family, may be the true monsters.
A Simpson's version of the Edgar Allan Poe tale, "The Raven", in which Homer is the main character, Lisa and Maggie are angels, Marge is the lost Lenore, and Bart is none other than the Raven, whose only line is "Nevermore".

As the episode comes to a close, Bart and Lisa consider the tales before going to bed, not knowing Homer was freaked out by all of the stories. Everybody goes to bed, but Homer has trouble sleeping that night, as he decides he hates Halloween when he hears the Raven outside.
The episode was written by John Swartzwelder, Jay Kogen, Wallace Wolodarsky and Sam Simon. Wesley Archer, Rich Moore and David Silverman directed. The episode is considered to be non-canon and takes place outside the normal continuity of the show. Part of the series' attraction to the writers is that they are able to break the rules and include violence and kill off characters, which they would not usually be able in a regular episode.
