Bud Graziano said "Bomber" is a former heavyweight boxing champion who retired to private life on a ship. Jerry Calà is instead a Lombard punter who finds himself always in trouble and one day gets really big. In fact, he unwittingly sets himself against a group of thugs who answer only to the orders of a new boxing champion who is making the rounds in the area with his victories. Even Bomber collides later with this sample name Rosco. So Bomber, suddenly awakened his passion for boxing, opening a gym for amateurs and begins to train the promising young George. Below Bomber organizes meetings which also participates Rosco which, being too strong, knocks the young George. After so many other battles, Bomber is on the verge of losing everything he has slowly and painstakingly put together and so decides to confront himself in combat Rosco.
