Scene: Harvard University, Cambridge, Massachusetts. A beautiful young girl studying to be a lawyer meets a handsome young, somewhat shy, medical student. They date frequently. Her roommate, also studying law is an attractive girl from Britain. The young people often visit local bars and restaurants and have a swell time. At one point they meet a somewhat agreeable, though grungy, street person. He appears to have no interest other than drugs. One day he comes to their apartment. He, or someone suggests that they all have an orgy: the beautiful law student, her somewhat shy handsome boyfriend, and the grungy street druggie. They ask the other young woman to join. She refuses. So they kill her in a violent, bloody fashion. Surprising since the students, at least, have never evidenced such behavior before. The beautiful young law student and her handsome somewhat shy boyfriend realize of course that this could be the end of their freedom and their careers, a disgrace to their families, the ruination of all future possibilities. But it was worth it because this girl wouldn't participate. Did you ever hear of anything so ridiculous?
