One evening, Hammer gives a ride to Christina, an attractive hitchhiker on a lonely country road, who has escaped from the nearby lunatic asylum. Thugs waylay them and force his car to crash. When Hammer returns to semi-consciousness, he hears Christina being tortured until she dies. Hammer, both for vengeance and in hopes that "something big" is behind it all, decides to pursue the case.
