When our narrator smashes his car into another and watches a man die in front of him, his sense of sexual possibilities in the world around him becomes detached. As he begins an affair with the dead man's wife, he finds himself drawn with increasing intensity to the mangled impacts of car crashes. Then he encounters Robert Vaughan, a former TV scientist turned nightmare angel of the expressway, who has gathered around him a collection of alienated crash victims and experiments with a series of erotic atrocities, each more sinister than the last. But Vaughan craves the ultimate crash - a head-on collision of blood, semen, engine coolant and iconic celebrity.
