A few years after a separation, the family of Anne including her two sons Vlad and Victor returned to their father, Anatoly, who fought in France. He tries to take the education of his sons, but the boys, accustomed to complete freedom, strongly oppose this. And then, as luck would appear, a distant relative of Anatolys wife Seva emerge and begins to teach the children good sense for their criminal 'concepts'...
