Talented surgeon Evgeny Lvovich Mishkin works in a small hospital in the town of Khatunitsy. His calling is to heal people. His work is essentially the meaning of Mishkin's life. He does not seek material wealth, rewards, honorary titles, or even a successful career. Patients are more important than anything else. Mishkin's wife, who is an art historian by education, does not understand this way of life and longs to return to Moscow. The conflict in the family has been brewing for a long time, but now it is ready to erupt into decisive actions. The wife poses a dilemma: the husband must choose between family or work. A new patient is admitted to the hospital, a complex case. Evgeny Lvovich has developed a unique surgical intervention technique that can help even in such circumstances. Mishkin's students and colleagues defend their doctoral dissertations, describing in theory the practical methods of the talented doctor. But the surgeon himself has no interest in academic degrees; at this time, he is busy saving lives.
