Mitya, after eight years of study at the St. Petersburg Medical University, returns to his native village of Ozernoe, somewhere in the vast south of Russia. His family, friends and the whole village in general are waiting for him with pride and impatience - after all, earmarked funds were spent on his studies, and a young doctor is also very much needed in the local hospital. But everyone is surprised to learn that Mitya is not a surgeon, not a dentist, and not even a urologist, but a psychologist-sexologist. Conservative residents do not accept Mitya, they call him a "pussy doctor", his own father threatens to recant, but Mitya does not give up. Because he knows how much help is needed for people who are unenlightened in sexual matters, who have tabooed the topic of "this very one" for generations and live in a world of myths, superstitions and prejudices.
