After an asteroid destroys the world as we know it, a new civilisation emerges inhabited by human beings and mutants, who look human but in fact possess super-human powers. Parish (Lance Henriksen) is the head of the new world order. Having already succeeded in consolidating his power and enslaving humanity, Parish is fanatically driven to establish a pure and perfect human society. He declares war on all mutants and unleashes his horde of merciless soldiers to exterminate the mutant population. In the midst of battle, a group of heroic mutants rise up to confront Parish.
