Piaffe

After her sister Zara has a nervous breakdown, introverted Eva has to take over her job as a sound producer. She sets a horse's behavior to music for a commercial - and becomes so passionate about her work that a tail grows out of her tailbone. And as the tail grows, so does Eva's sexual desire. She begins an S&M affair with a botanist researching ferns and suddenly experiences her body in a way she has never felt before.
