A group of wild young people, after enjoying antics in a jeep, kidnap a wealthy woman driver (Bunjaku Han) by shooting out her car tires. They set her free but she forms an attraction to a member of the group. They begin a romance and she tells him she is the mistress of the leader of a religious organization called Shinkyo Gakkai.
The group dig up a stash of weapons buried in a school courtyard at the end of the second world war. They plan to rob the organization.
