Surgeon Alim Sabirov, fearing for the patient’s life, offers his services to Valieva, a protégé of the head of the hospital, who is preparing to defend her dissertation. Due to an unsuccessful operation, the patient dies. But Valieva intends to continue her career in surgery and asks Sabirov to sign a certificate of death, allegedly due to heart failure. The hero does not sign the conclusion and, moreover, begins a decisive fight against the unrest in the hospital.
