In the film, a dysfunctional family squabbling causes a young boy to lose his festive spirit. Doing so unleashes the wrath of Krampus, a fearsome, horned demonic beast in ancient European folklore who punishes naughty children at Christmas time. As Krampus lays siege to the neighborhood, the family must band together to save one another from a monstrous fate.

The Krampus is an old Christian character from old world Catholic Christmas traditions. The Krampus is one of the variations of St Nicholas’s helpers; a tradition where another character is assigned St Nicholas’s naughty list duties. The Krampus is a horned anthropomorphic goat figure with one human foot and a very long tongue who, in Central and Eastern Alpine folkloric tradition Christianity, is said to accompany Saint Nicholas on visits to children during the night of 5 December, immediately before the Feast of St. Nicholas on 6 December. The Krampus knocks on the doors of children’s homes to warn them to be good, or otherwise he will return on Christmas Eve with St. Nicholas. In this tradition, Saint Nicholas rewards well-behaved children with small gifts, while Krampus punishes badly-behaved ones with birch rods.
