Kiroku boards with a Roman Catholic family and falls for the daughter Michiko. He ignores his feelings, joins a gang, gets in fights and, eventually, becomes involved with the radical Kita Ikki group.
A hit man working for the Yakuza double crosses his employers and flees with a cache of diamonds from the latest heist. Injured and hiding in the mountain regions of Spain, with Japanese assassins in hot pursuit, he takes refuge in the home of a local doctor and his two daughters who nurse him back to health and hide him from his pursuers, taking drastic and murderous measures to protect him... for they have plans of their own in store for their current guest.
Set in a Shinjuku bathhouse brothel, the film uncovers the sexual eccentricities of everyday people. Focusing on three female prostitutes, the colorful, unpredictable look into the hidden underbelly of Japanese nightlife is playful but also unafraid to explore the darker sides of the business. The fleeting nature of relationships in such an environment and the consequences of toying with feelings are presented with a melancholy tinge.
