In this Japanese film, the Shimoda police station gets a new judo instructor who soon finds himself in love with the previous instructor's daughter. This makes another student so jealous that he challenges the new sensei to a duel. The young upstart is quickly put into his place. Later the instructor loses his job for fighting with naval officers. The young man again challenges him, and this time he wins. He also wins the young woman's heart. ~ Sandra Brennan, Rovi
