A group of Swedish tourists are on the way to a Russian village to witness the so called 'Festivity of Neptunus', in which the inhabitants take a dive in a hole in the ice. This tradition, however, does not exist at all. The inhabitants try to make a good impression by starting the 'tradition' to please the tourists.
