Mother Keiko (Mirai Hirooka) appears to live a peaceful life with her prep school student son, but inwardly, she's consumed by uncontrollable lustful fantasies. After losing her husband several years ago, she's been completely starved of male attention and finds herself attracted to nearly every man she encounters—be it the delivery courier or the dry cleaner owner. Her fantasies eventually turn toward her own son, leading to an intense and taboo family affair.
