Santa turns into a werewolf on Christmas Eve, and wreaks havoc in a small seaside town - Lucy has a show called 'Monster Hunter's' on Youtube, but it's not doing too great with just a few viewers following her. That is until, on Christmas Eve, her camera witnesses Santa get bit by a werewolf in the local park, before turning into a werewolf himself. Lucy and her family then set off on a Christmas Eve adventure to somehow save Christmas, armed with just a rusty ice skate and a vague understanding of how werewolves operate.
