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.

Krampus hits theaters on Dec. 4.
