美雏成行 Pretty Maids All in a Row (1971)

One of the most politically incorrect films of all time, Pretty Maids All In a Row is easily Roger Vadim's most audacious film. Scripted by Gene Roddenberry, it focuses on the strange happenings taking place at an upmarket California high school. Someone is killing the nubile students of an otherwise picture-perfect high school. A cynical detective visits the building to find out who's committing the murders. He and his dim partner interrogate the students and staff, including a fidgety principal. They also encounter two faculty members -- slutty guidance counselor Tiger and horny teacher Miss Smith -- who have been saving "personal time" for their students. Meanwhile, Miss Smith discovers she has in her class a shy teen afraid of his burgeoning manhood. So she plans to keep him after class to help him overcome his timidity.
