After the mysterious death of his father, Yegor returns to his native village to persuade his younger brother to quickly sell the joint inheritance to a local entrepreneur. However, the more Egor is immersed in what is happening, the more clearly he understands that he, his brother and the legacy of the family are in great danger, from which he will have to defend himself with weapons in his hands. Meanwhile, he himself increasingly sees Zemun - a mystical cow, which, according to legend, comes for the souls of the shepherds after their death.
