Tom Rath is a suburban father and husband haunted by his memories of World War II, including a wartime romance with Italian village girl Maria, which resulted in an illegitimate son he's never seen. Pressed by his unhappy wife to get a higher-paying job, Rath goes to work as a public relations man for television network president Ralph Hopkins. Drawn into poisonous office politics, Tom finds he must choose his career or his family.
Unfortunately the movie The Man in the Gray Flannel Suit is not yet available on HBO Max.
