Tonii is a salesman at a mortgage company, and although he is in a romantic relationship with Haruko, a typist at the company, they cannot get married because they have nowhere to live. Growing impatient, Haruko declares, “As long as he can support us, I’d even marry an old man,” leaving Tonii deeply troubled.

After Ryusaku Nishikawa and his girlfriend Katsuko are attacked by a gang, he trains in karate to seek revenge. Years later, Ryusaku is a skilled martial artist preparing for an inter-school match, but his past resurfaces when Katsuko, now involved with the gang, brings tragedy. In a final confrontation, Ryusaku faces the gang and finds redemption through his karate, with the support of his friends.
