Bomber is a 1982 comedy film directed by Michele Lupo, featuring Bud Spencer and Kallie Knoetze.
Bud Graziano, the title's "Bomber" character, is a former heavyweight boxing champion who retired to private life on a ship.
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.
Bomber suddenly feels his passion for boxing reawakened, so he opens a gym for amateurs and begins to train the promising young George.
After many other battles, Bomber is on the verge of losing everything he has slowly and painstakingly put together and thus decides to confront Rosco personally in a boxing contest.
