A young biker on the run from his domineering tycoon dad ends up hiding out in the Addams house, and the Addamses couldn't be happier.

Uncle Fester applies for a job as an insurance salesman with the same company which is threatening to cancel the Addams' policy.

Fester takes a correspondence course and boldly storms the gates of the business world. Roy Roberts appears as business executive Thaddeus Logan.

The Addams mansion becomes a battlefield when Gomez and Morticia tell Grandmama and Uncle Fester that they think they are spoiling Pugsley and Wednesday.

A former truant officer named Sam Hilliard heads a private school where Wednesday and Pugsley are enrolled. When Hilliard breaks under the strain of dealing with the Addams children, Gomez buys the school.
