The Square Jungle

Pat Quaid, an alcoholic San Francisco widower, ends up in jail.

When he can't borrow it, Eddie enters an amateur fight contest and wins it.

Pat Quaid, once a promising prizefighter, urges his son to give it a try professionally.

Bernie's work with Eddie eventually leads to a fight with Al Gorski for the middleweight championship.

He feels "dead inside," but when Julie is able to get him back to a boxing arena, Eddie finds that Gorski and the spectators all have forgiven him.
