McGrath publishes children's book and Uncle Bump is one of the best sellers, but Greg, who is Uncle Bump, drinks too much and hasn't started his next book. Martha won a contest to illustrate the book and the first thing Greg does is get her soused. To keep her there to illustrate, John gets a juvenile delinquent named Danny to play his son and show how much pressure he is under. The ploy works at first, but Greg's heart was broken by Tillie, and Martha may be the girl who makes him forget all about her.
