I'm looking for an old horror movie from the 70's or early 80's that I don't know the name of. Goes something like this: a group of
young people go to a house that is somewhat isolated and they start being murdered one by one. Can't say that I remember much but at the end only one escapes and it is a woman. While she was escaping the killer jumps on the hood of the car and she kills him by letting the car go into a fence. The tips of the fence go through the body of the killer and that's how he dies. Can anyone help with this???
