Horse and Woman and Dog (1990)

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.

Sato centers his attention on the psycho-sexual deterioration of his protagonists.The film is quite unsettling with two graphic bestiality scenes involving a dog and a horse.There is also plenty of perverse sex on display.
