Uma to onna to inu 1990

Directed by Hisayasu Satō

Three social outcasts who live near the seaside interact with each other in increasingly disturbing ways. The trio of characters are a woman who has killed her sister, a man who enjoys necrophilia, and a female amnesiac. The first woman engages in sadistic pursuits such as capturing young women at the beach to force them to engage in sexual activities, including copulation with a horse and a dog.
