The film is a black comedy and satire of 1950s sitcoms set in a dystopic future populated by bizarre, tentacled creatures which function dually as household appliances and food.

The film takes place in a dark world full of pipes, tubes, corridors and a mysterious "edge" that misbehaving children are threatened with being thrown over.

Dinner begins, with some idle chitchat about work, degrading into a discussion of the dangers of rationalism, and finally coming back to Mr. Hollowhead's desired promotion.

The party has been raided by police after the party-goers tapped into a highly restricted tube, and Cindy was taken into custody under the intoxicating influence of two pounds of softening cream.

Oldest son Bud returns after having been booed out of the party because of his new songs, and Mr. Crabneck wakes up once more before finally expiring at the sight of Cindy's drunken state.
