University students Sudo and Mori make money by picking up rich girls in dance clubs and conning them into giving them cash. Mori is the brains of the operation, and Sudo is the suave dancer who picks up the girls. Sudo becomes gradually involved with three different girls and is drawn into the gangster milieu, which he seems unable to resist even though he is responsible for his mother, grandmother, and sister Masako. In this world of bad boys and girls, Masako is the pillar of strength and moral virtue who finally enables Mori to straighten out.
