Only Helena, a gutsy investigator on the trail of the notorious war-criminal Klausener, accepts the reality of that they are facing a battalion of Nazi Storm-Troopers, a veritable zombie army on the march. With the help of Wallace, a man who's been chasing Nazi secrets for years, the two of them team up with a Special Forces Unit to venture deep behind enemy lines.
