It's Christmas Eve, and a dysfunctional family is preparing to celebrate the festivities. However, after a buildup of tensions and a lack of Christmas spirit, young Max, overwhelmed by the negativity surrounding him, loses faith in the magic of Christmas. In a fit of frustration, he destroys his letter to Santa Claus, accidentally unleashing a dark force that had been lying dormant: a legendary figure who punishes those who do not celebrate the holiday as they should.
As the night progresses, the family becomes trapped by an unrelenting snowstorm, and mysterious incidents begin to occur. Soon, they realize they are not alone; terrifying creatures, led by Krampus himself, begin to stalk them. This sinister character comes to take away those who have forgotten the true meaning of Christmas. With chaos unleashed, the family must come together and overcome their differences to fight against the forces of evil before it’s too late.

In this struggle for survival, it will be seen whether the spirit of the season is enough to restore the joy and everything they have lost. The night becomes a memorable and terrifying journey toward family redemption.
