DAU. Katya Tanya

Katya, a young librarian, believes in love, but her ideals are crushed by reality. After a string of disappointing affairs, Katya finally finds tenderness and understanding in the arms of her colleague, a journalist called Tanya. But then the First Department interferes: the state security services see this relationship as unacceptable for a Soviet woman.
