Wilby Daniels is now a successful attorney who is married to Betty, and they have a son named Brian. Returning to the town of Medfield from a vacation, the family discovers that they have been robbed of almost all their possessions and Wilby blames the local district attorney John Slade, who is reputed to have connections with organized crime, particularly with warehouse owner Edward "Fast Eddie" Roshak. After being robbed a second time later that night (along with their Navy admiral neighbor), Wilby vows to run for district attorney to make his town safe again. All Wilby has to do is keep his secret from his wife, if a secret phrase is said, his ring turns him into a shaggy dog.
