Ginjiro finds that it has become impossible to collect debts when even his regular clients have been conned out of their savings. He discovers that Sugiura gang underboss Domoto is behind these schemes. Domoto wants to take over the gang and tries to ruin Yukino, the real boss’s widow and the gang’s acting head, by sabotaging a resort hotel project with the help of a thug named Kawatani. Ginjiro, who has lent money for the project, is furious when he learns about Domoto’s schemes and goes into action.
