Krampus

Three days before Christmas, the Engel family prepares for the holidays amidst their dysfunction. Max still believes in Santa Claus and writes him a letter with his Omi's encouragement, but after being mocked by his cousins, he lashes out and tears up the letter. Unbeknownst to him, this loss of festive spirit has unleashed the wrath of Krampus, an ancient demon who punishes non-believers during Christmas time.
