Brokeback Karate

A man is mugged and beaten by two young women who take the money from his wallet. A friend stops beside the beaten man, who's prone on the sidewalk; the passerby hands him the business card for Brokeback Karate. He enrolls, but at first he's a poor student. His sensei emphasizes pelvic thrusts. Will this mentoring lead to any changes in our man's life? What about the muggers?
