Gynecologist-reproductologist Olga is a "shoemaker without boots." She has helped many women find the happiness of motherhood, but she herself cannot get pregnant from her beloved husband - the couple has genetic incompatibility. Pavel raised Olga's son from her first marriage, but is obsessed with the idea of having his own child. The next IVF attempt is successful - Pavel is happy, but Olga is sick and the pregnancy is in danger.
