A woman mentions that she has been attacked by a man when she was undressing after her karate lesson and that she killed him. She explains that her misogynist master told her that it was her fault. At some point, all the karate students undress to stretch. The new recruit (main character) is led to a small room apart and told that he has to do something special to be part of the group. The master then opens the door and the only woman of the dojo is standing there waiting. They only stretch together but the undertone is quite heavy. More generally, the film sets an atmosphere recalling sects and it contains several shots hinting at the fact that the master exerts a sexual domination over the main character.
