His voice describes his struggles to grow up and become a successful writer in a world filled with unscrupulous businesspeople, conniving relatives, and other assorted roadblocks. Rudy’s quest for fame and fortune, including an unsuccessful trip to Hollywood, is thwarted by his own immaturity, by an unsympathetic publisher (Plaster), and by his own family: a domineering mother; an overindulgent father; a materialistic sister (Julie); and a boorish, opinionated brother-in-law (Leon), who is a successful psychoanalyst with writing aspirations of his own. As Rudy struggles to make a living at an insurance company, Leon’s writing career blossoms. Leon’s book, published by Edwin Plaster who has rejected Rudy’s novels countless times, becomes a best-seller. A few months later, Julie informs the family that Leon is being sued for plagiarism and during the trial scene, Leon and Plaster are found guilty.

Plaster phones Rudy to tell him that he has found a backer and is planning to publish a book based on Leon’s life. Plaster wants Rudy to write it and makes a very attractive offer. This is not the type of writer Rudy had hoped to become, but the years of humiliation have taken their toll.
