The end of the XIX century. A girl was killed. The mother and brother of the deceased find the villain and are going to punish him, but the villain does not care — he is not afraid of death. Then the mother of the murdered girl decides to "re-educate" this person, postponing revenge until he begins to appreciate at least something in life. And a few years later, a dance teacher arrives at the estate, who should become a tutor for a prisoner sentenced to a deferred execution.
