25 days, 25 chapters. This December, the countdown to Christmas will chill you to the bone.

Hoping to bring his family closer together, Adam Gray arranges a holiday in a remote cabin on a snowy mountain. Things take a dark turn, however, when someone starts leaving them gifts in the Christmas stocking that’s been mounted on the barn door.

Every morning, it’s something new, and with each passing day, the contents become more and more terrifying. Soon, the family comes to a spine-chilling realization: they’ve been dragged into a deadly game and if they want to survive, they will have to fight.

And they’re up against the most deranged ‘Secret Santa’ the world has ever seen.
