1945. A U.S. army cargo aircraft loses management and violently crashes behind enemy strains in the midst of the German black forest. Main Johnson sends a squad of his bravest troopers on a rescue mission to retrieve the top-secret materials the aircraft was carrying, led by Sergeants Brewer and Walsh. They quickly uncover hanged Nazi troopers and different lifeless our bodies bearing historical, magical symbols. Abruptly their compasses fail, their perceptions twist and straying from the group results in profound horrors as they're attacked by a robust, supernatural drive.
