It's 1965 and Farben Hospital is the leading medical facility in Frankfurt am Main, Germany. One by one patients at Farben begin to die and their connection to the Nazi SS Shutzstaffel decades before lead Inspektor Richard Eckner to believe a murderer is on the loose. As the bodies pile up, Eckner digs deeper for clues. Unusual markings on the victims steer him to a legendary tale of a killer known as The Mask. Time closes in when the plot for revenge turns personal, and Eckner falls prey to a killer with nothing to loose.
