Dusha, a young dancer and dance instructor, is torn between a dominant mother, an absent father and a married lover. She is sinking into a typical crisis of the thirties, which only gets worse when she starts suspecting that someone has been following her and invading her privacy. Growing increasingly lonesome and exhausted, she realizes that her relationship with her married and inattentive lover has no future and decides to leave him, even though she is pregnant with his child. Even her overly self-confident and sexually vibrant mother is getting ready to be a loving grandmother. This positive change was actually triggered by Dusha′s secret admirer, someone she first regarded as a potential danger and a distasteful voyeur. He gradually finds a way to her heart and convinces her that there is meaningful life after youth. He offers Dusha a chance to rethink her attitudes toward life and make a fresh start. She decides to keep the baby, stay friends with her two male friends, and live the life of a single mother.
