Yaroslavl, 1974. Two high-profile and violent crimes are taking place in the city. The investigation is being handled by the uncompromising investigator for particularly important cases of the prosecutor's office, Egor Tabolin. The threads of these crimes lead to one person — the head physician of the psychiatric hospital, Mikhail Nagornykh, and his deputy Vaganov, in whose hospital several mysterious deaths have occurred in recent years.

Peter Andreevich, an outstanding doctor, heads the N. I. Pirogov Hospital. His daughter Kira, a brilliant surgeon on the verge of burnout, also works here. Novice doctors come to work at the hospital, whom Peter Andreevich directs to her for training. Kira takes them with hostility, for which she quickly becomes a "bitch" in the eyes of newcomers. None of them suspects that behind her nagging lies the desire to make them real professionals. For Kira, her career comes first, except for her, she has no friends, no husband, no children — only a married colleague-lover Ignat, who is in no hurry to get divorced. The only one who saw Kira as a real girl behind the external severity was the new doctor Egor.

To realize her dreams and escape from her father, who began dictating his rules to her after her mother's death, Rita gets a job as a nurse for the daughter of a former teacher.
