Lena is a talented obstetrician-gynecologist; her husband is an artist in a provincial drama theater. They are very close to each other and there is a lot of tenderness between them, but no sex. Lena suspects Serioja of having an extra-marital relationship, but she suffers in silence and does not show her jealousy. Instead of taking stock with her husband of their relationships, Lena also begins to cheat on him with passing men. Little by little, Lena loses control of this parallel life which practically redraws her main life.
