US expatriate Bobby Ives is an aimless Vietnam veteran living in London with his girlfriend. The extremely volatile Ives is obsessed with two strange events in his past: the fact that he was declared dead in Vietnam via administrative error, and the time he experienced a vivid waking dream in which he became a zombie. Ives finds himself becoming more susceptible to uncontrolled rage; he also experiences quasi-fugue states where he lets that rage overwhelm him. In the midst of such a fugue state, he's capable of great violence. His girlfriend dies as the result of one of his rages; other victims soon follow.
