Young Larry has all the virtues of the old samurai: self-control and discipline, endurance, concentration and sense of honour. His strength of character also convinces the great Akai Kimura, the master of all masters and multiple martial arts world champion from the "Land of the Rising Sun". He becomes Larry's trainer and tries to prepare him for a fight with Joe Carson in the shortest possible time. A grueling training begins. Larry gives everything he has and very quickly becomes a real karate fighter. After he has abused and tormented himself beyond compare, his master shows him the secret of the "dragon punch" and Larry is ready for his big fight. But will his will and the short training alone be enough to stand up to Joe Carson's years of experience, deviousness and killer instinct?
