Polyot nochnoy babochki (1992)

Hiding from the paternal appearance of a police captain, a currency prostitute finds herself in the room of a quiet, modest pianist from the United States, who took part in a competition in this resort town by the sea. The naive young man, delighted with the adventure and the fact that his strict mentor left him at least for the night, was carried away by a pretty and cheerful girl. So the "night butterfly" finds great, sincere love.
