The core theme of the Blue Hour is the transitional period of the 1990s when the modern lifestyle clashes with the conservative values of the very people who have migrated to the capital of the country. It is centrally depicted through the conflicting relationship between a mother and a daughter. Petra, who has made a life for herself in the big city has a crush on her office co-worker Igor and is trying hard to start a meaningful relationship. Her mother's visit from a provincial town in the south not only jeopardizes her efforts, but adds to the already palpable disconnect between the mother and daughter. But soon it will be New Year's Eve, and everybody is hoping for the best.
