Spurred by the disappearance of a newly-wed husband, three women in post-war Japan are drawn into a murder mystery.
Kintaro is a reformed delinquent, the former leader of a biker gang who has gone straight. Working at a construction company, his unorthodox tactics cause trouble with his colleagues. He is transferred to a tiny countryside branch, where he butts heads with his lazy superior until the two men discover a plot by the competition to put the construction company out of bussiness. With the help of his old biker friends, Kintaro prepares to confront the masterminds behind the scheme.
Kintaro Yajima comes to Tokyo and is hired by Yamato Construction Company when he saves the life of the company's CEO. A former leader of a motorcycle gang, Kintaro is known for his highly principled and forthright way of dealing with matters and is never afraid to tell his superiors exactly what he thinks. This has a tendency of irritating some; but when corruption from within the company begins to surface, he may be the only one who can stand up to it.
