Kaisa is a relentless overachiever and it’s beginning to affect her job as an elementary school teacher. To make everything worse Kaisa has to work with the best teacher in the world, Anneli, whose perfection is as effortless and relaxed as a summer breeze. Whatever Kaisa chooses to do, Anneli does it better, at least in the race that Kaisa is orchestrating mostly inside her head. Together with her class Kaisa has produced a magnificent Christmas show for the school holiday celebrations, but Anneli has an ace up her sleeve. Things get bloody when the results of the teachers’ lounge gingerbread house competition are announced. Add to this the lengthy history that the ladies share that reaches far beyond their careers together.
