In the depths of a dense winter forest, an old little witch lives. The animals in the forest like her, because she has never caused anyone suffering. But she has a small mistake: sometimes greed overcomes her - so also on a Christmas evening. She wants more gifts than she deserves, so Santa decides not to give her a gift at all this year. The witch chases after Santa's balloon to tear him a gift. But she does not succeed, instead her witch broom breaks during the wild hunt. Sadly, the witch sneaks home. Unhappy and lonely, she sits in her gloomy witch apartment and is ashamed of her greedy behavior. Suddenly Santa is standing in front of her. He is not evil, but gives her a new witch broom and a red witch cat. So it happens that Hex' and Santa celebrate Christmas together and make music deep into the night.
