It's the week before the Land of Christmas Annual Variety Show, and preparations are in full-swing. That is until Ahora of the jigsaw factory mysteriously disappears. Finklefoot is once again called upon by The Fat Bastard to investigate Ahora's mysterious disappearance, which leads him back to an old enemy and the horrors of Christmas past. Meanwhile, Rudolph has attracted the unwanted attention of Merthyr Titful, a seemingly harmless reindeer. She laughs at his jokes, which is helpful at first because he's about to take to the stage at the variety show to test out his new material. When Merthyr's affection turns to obsession, Rudolph tries to distance himself from her. Which is where Merthyr's campaign of terror begins. And Hell hath no fury like a mad reindeer scorned.
