Restless Lucy really likes to have fun in the company of friends. The girl does not always get to "have fun" in full, due to a wide variety of reasons that arise, according to the laws of meanness, at the most unexpected moment. One day, on the eve of the Christmas holidays, the grandmother informed her granddaughter that she would not be able to come to visit. This news both disappointed and pleased Lucy at the same time.

She will not see her relative, but she will have the opportunity to arrange a grand celebration that can cheer up and recharge with positive energy. The guests gathered at the event in a thematically decorated room do not share the festive mood of the hostess of the evening at all. Meanwhile, Charlie Brown, immersed in his own troubles, is trying with all his might to fulfill one of his promises made to friends exactly twelve months ago. This must be done before the hour hands point to midnight.
