Cabaret girl Tomoyo (Minami Natsuki) is on her way to work when she is approached by a homeless man and stops to see her father, Takayuki (Tadashi Naito), who left his family ten years ago, leaving them in debt; office worker Yuko (Shoko Kudo) is at a loss in a park after her boss, Kondo (Yuya Takayama), with whom she had an affair, abducts her infant son. These three women with a history of their own meet by chance and hit it off. The girls, feeling burnt out, are at Tomoyo's behest.
