The year is 1948. Former WWII German spy Erika Lehmann now works for the CIA along with Heinrich Himmler's top Gestapo henchman, Axel Ryker. Despite Erika's loathing for the murderous Ryker, their CIA controller forces her to join forces with the brutal former Gestapo hitman to stop a dire threat to the population of Denver, Colorado, by a skilled and ruthless mercenary. If this hired soldier and his team are successful, it could cost thousands of innocent American men, women, and children their lives.
