A resident of Rostov-on-Don recognized her own sister in a psychologist from Moscow. That's just the psychologist does not believe that he can be a stranger in his family. The psychologist's mother assures: she did not adopt the girl, but gave birth to her herself. Is the striking resemblance of the two women a mere coincidence?

21 years ago, a man named Alexander woke up with a broken head and in a pool of blood in Khabarovsk. In Alexander, who lost his memory from the Far East, a widow from the Kemerovo region recognized her... husband. Two decades ago, she was informed that her husband drowned in a storm off the coast of Kamchatka, and his fish-eaten body is impossible to recognize. Is it possible that a drowned fisherman and a man who has lost his memory are the same person and his wife and son have been waiting for him all these years?
