Seventeen-year-old Paul Salvage competed and won the honor of becoming that Vessel. When scientists implant the particles in Paul, the evil transforms him, cures his amnesia, and makes him remember his own act of rage. With this revelation, Paul questions whether he’ll be able to control the devil particles coursing through him.

The government-backed scientists keep Paul in a cave laboratory to monitor him and test his new super-human abilities. They intend to confine him there indefinitely, but Paul wants to leave to aid in the reconstruction of the new society and to be with his girlfriend and grieving father. Frustrated, Paul uses his devil particle-enhanced brain to manipulate them into letting him go home for a weekend.

Will Paul be able to save the world, or will he destroy it?
