The corpse of a girl who died of blood loss as a result of multiple minor wounds was found in the park. Andrey Izvarin, a history teacher, undertakes to help the investigation. He developed a unique theory of criminal cyclicity, according to which crimes from the past are repeated after dozens, and sometimes hundreds of years: the same tool, the same method, but most importantly - the same motive.

After a difficult conversation with Izvarin, Rybakova leaves for a hotel near Moscow. The same night, a murder takes place in the hotel, and Rybakova herself is among the suspects. Only a historian can find the real criminal and prove her innocence.
