Monika is spending the holidays alone this year, hiding out in her late grandmother's beach house. She plans to spend the season with her anti-anxiety meds and a bottle of wine until an unexpected visitor breaks in. Prepared to fight for her life, Monika uses her grandmother's old handgun to shoot the intruder only to realize it's not a man. It's Krampus the Yule Devil himself. Krampus sweeps Monika up in his sack and carries her back to his realm where she is in for a whirlwind night of pain and pleasure. But there is more to Krampus than meets the eye, and there is a darkness in Monika that she's always been dying to unleash. Not everything is as black and white as 'naughty' and 'nice.'
