Ralph Kramden is a perpetually flustered but eternally optimistic New York City bus driver living with his wife, Alice, in a small Brooklyn apartment. Ralph's best friend is sanitation worker Ed Norton, who lives in the same building with wife Trixie.

Ralph and Ed take care of an abandoned baby left on Ralph's bus; Ralph thinks a turkey ate Alice's missing wedding ring.

Ralph takes over the janitor's job in his building and finds that it is easier to make complaints than receive them.

Norton and Ralph become business partners.

Alice gets jealous when blackmailers fake a photo of Ralph fooling around with a Spanish local in Madrid.
