A swinging bachelor runs afoul of a Nazi biker gang and it begins a circle of escalating scenes of vengeance. I watched this movie because I read it had a grindhouse feel, and there is some of that, but there is also a lot of softcore romance. The bikers eventually kill the bachelor's whole family, and he hunts them down and kills them until he gets home and the final biker has a bomb that kills them both. I don't plan on watching it again.
