In a future where every citizen is implanted with a chip capable of controlling everything from emotions to directions; a routine update backfires, causing a cyber apocalypse. Wiping out most of humanity, five strangers miraculously survive, now forced to live hidden in a bunker with their implants ripped from their spines.
A brutal mugging leaves Grey Trace paralyzed in the hospital and his beloved wife dead. A billionaire inventor soon offers Trace a cure — an artificial intelligence implant called STEM that will enhance his body. Now able to walk, Grey finds that he also has superhuman strength and agility — skills he uses to seek revenge against the thugs who destroyed his life.
