Igor (35) is a successful resuscitator physician. Igor's colleague Sveta (33) is a single mother who is raising a four year old daughter Dasha. Igor and Sveta are friends who confide in each other: they share a few years of work, but during all this time Igor never looked at her as a woman, only as a friend and colleague. In Sveta's life appears a new love - a hospital administrator, Anton (32). Igor goes to the store and meets 30 year old Olga there.
