Tang Lung (Bruce Lee), a young man from Hong Kong, travels to Rome to help a family friend (Nora Miao) fight off a gang of thugs who are trying to take over her restaurant by any means necessary. After Tang Lung easily fends off the first group of thugs, the gangster boss calls in reinforcements in the form of an American and a Japanese martial arts expert (Bob Wall and Hapkido master Hwang In-shik). When they fail to neutralize Tang Lung, the brutal American fighter Colt (Chuck Norris) awaits him. The clash of the titans takes place in the Colosseum in Rome.
