Behind the Door

Hobart Bosworth stars as Oscar Krug, a working-class American, who is persecuted for his German ancestry after war is declared. Driven by patriotism, Krug enlists and goes to sea. However, tragedy strikes when his wife (Jane Novak) sneaks aboard his ship and is captured following a German U-boat attack. Krug's single-minded quest for vengeance against the sadistic German submarine commander (Wallace Beery) leads to the film's shocking and brutal climax. (Flicker Alley)
