In late-1970s suburban London, Chris and Marion have settled into a comfortable yet all-too-predictable middle-class existence. Chris receives an unexpected visit from his free-spirited friend Toni, a reunion that reminds him of a more carefree time in 1960s Paris. Now, with lingering doubts about his marriage bubbling up, Chris must make the choice between revisiting his youthful abandon with Toni or facing the here and now with Marion.

Britta, the new girl in school Highland, has reason to be jubilant this Christmas: Her sadness has served to invoke Holly Boy, the holiday spirit, waking him from his deep slumber imposed by a dark elf, King Otto. This sets off a battle earthly and supernatural fury that develop simultaneously. The Young Britta must face her fears and death defying aerial action in the holidays from school, while Holly Boy has to fight against the forces of evil. Both battles must escape to save their lives, school, and the sacred forest, although, in reality, what is really at stake is the Christmas and values.
