Miia (Pirjo Lonka) has organized a company party, but the atmosphere is ruined when Katja (Seidi Haarla) reveals partly by accident that the boss had groped her after the previous spring party. People start speculating about the motives and timing of Katja's revelation. Which is more important, the truth or the festive spirit? Festive Spirit (Juhlatunnelma) is directed by Jenni Toivoniemi and written by Jenni Toivoniemi and Kirsikka Saari, and it is part of the film anthology Force of Habit (Yksittäistapaus).
