In 1943, during World War II, three American soldiers drunkenly carry out an unspeakable act of carnal violence on a local nun. Turned away from her convent by the Mother Superior who blames the victim of this violation for sinning, the distressed nun wanders the local forest in turmoil. Krampus hears her cries and provides swift and brutal revenge against the wicked soldiers. However, violent vengeance comes with a soulful price to pay.
