In 1995, the CIA made a breakthrough that they hid from the world because it would change everything in modern science-but some secrets can't stay hidden. A rogue force has learned how to make disembodied minds capable of lethal action. Ghosts have been weaponized, and now a Russian general has infiltrated the U.S. with a squad of "berzerkers"-an army that can't be killed because they're already dead. Only one person knew the general's plans, but she died in a car crash. The only person who can communicate with her is the cop who was at her side when she died-and now he must race to stop a force that could end life as we know it.
