Karen (50), a retired teacher and father of a teenage girl, wants to become a horse. He travels to the US in order to meet his trainer who introduces him to the art of pony-play. Seen from the outside, it looks like nothing but fetish role-play. But for Karen, it is above all else a spiritual quest and a strong desire to move away from the human world. Karen wears his leather outfit, hooves on his hands and feet, even a mane, with the firm intent of doing away with his 'human' being to reveal his 'horse' being.
