Werewolf Santa.

Lucy has a social media channel where she hunts evidence of actual monsters, but it’s not doing great, with just a few viewers following her disappointing posts. Everything changes on Christmas Eve when her camera witnesses Santa getting bitten by a werewolf before he turns lycanthrope himself! As Werewolf Santa starts wreaking bloody havoc in their seaside town, Lucy and her bickering family set off on a madcap adventure armed with a rusty skate and a vague understanding of how to kill werewolves gained from her collection of horror comics. The Beast must die to save Christmas!
