Sex Hunter opens with an exquisitely photographed performance of Swan Lake featuring Miki as the prima ballerina. After the recital she receives numerous bouquets, one of which is from Akiko, a renowned ballerina who runs an exclusive ballet school. On her way home after the show Miki is approached by Akiko who invites her to join her academy. Miki agrees and is brought to the isolated location at once to begin her training.
Once there Miki quickly discovers there is more to this school than meets the eye as she is thrown headfirst into a deviant cocktail of rape, incest, group sex, sadomasochism, and Coca Cola enemas.
