On days off from swimming class, an underground photo shoot takes place. It began when a golf-obsessed father, fond of sexual pranks, devised an abnormal plan to use his daughter to repay debts. Initially, it was a casual photo session inviting close friends, having the girl strike erotic poses. But as profits failed to meet expectations, it gradually evolved into a full-scale production, eventually transforming into a brothel-like operation disguised as a photo shoot. The illegal activities leaked out, sparking a major scandal. *No performers in this work are under 18 years of age.
