A courageous but naive boy from one of Japan's smaller islands goes to seek his fortune in Tokyo and ends up involved in Yakuza violence. Yoichi's descent into crime begins after he is befriended by the more worldly Michio who helps his new friend find work in a night club run by the Yakuza. Unfortunately, the boy messes up and enrages the club owner. He simultaneously makes a favorable impression upon a crime boss who likes the rude boy's insolence and refusal to bow to the brutish club owner. The Yakuza hires both Yoichi and Michio as thugs and assigns them to collect gambling debts. The two get into trouble when they begin interfering with their drug-addicted boss's relationship with his moll.
