Martial arts champion Em retires to live peacefully in her desert home and raise her younger brother Barry. That peace is shattered in the roar of motorcycle engines, gunfire, and the appearance of Deathking Ra, the demon god of broken bones. Thrown through time and marked for death by Ra, Em’s only hope for survival is with the help of her two incarnations from past lives. Unyielding in mind and body, Em’s blood-soaked quest to return home will take her beyond the doors of death itself.
