Watch Santa’s Shadow Unleash Christmas Terror in the Trailer for Krampus

He sees you when you’re sleeping, and he knows when you’re awake. He knows if you’ve been bad or good, but it probably won’t matter once Krampus has come to town.

Legendary has unveiled the first official trailer for Krampus, the new Christmas horror film releasing later this year. The new look at the film showcases the family at the heart of it all, including Adam Scott, Toni Collettee, Allison Tolman, and David Koechner. But the already less-than-happy family’s holiday festivities take a turn for the even worse when the evil spirit of Krampus is unleashed upon them and they must come together to fight for their survival.

Krampus hits theaters on Dec. 4.
