Midwife Lena, a loving wife, is driven towards a string of infidelities after her husband continues to neglect her.

By the age of 30, Lena was able to achieve good results in life. She worked as an obstetrician-gynecologist. Colleagues respected, and happy patients tried to thank her. Her personal life also developed quite safely. Husband Sergei worked as an actor in a drama theater, showed concern and did not interfere in affairs, but recently she began to notice serious changes in his behavior. Another fact is that they did not have sex. One day she reads one of her husband's text messages, she is convinced he is cheating on her. At one point, she does not stand up and in revenge cheats with a little-known man. For her, a new world unexpectedly opens up, filled with passion and incredible emotions, which she uses for her emotional state. But constant betrayal is becoming an integral part of double life.

Lena (Gromova) is a talented midwife and gynaecologist, her husband Serezha (Pal) is an actor at a provincial drama theatre. They are close and gentle with each other, but there is no sex. Lena suspects that Serezha has an affair, but she worries quietly and does not reveal her jealousy. Instead of sorting out her relationship with her husband, Lena starts to betray him with chance acquaintances. Gradually Lena's parallel life gets out of control and changes her original life.
