There is a demon of gluttony in legends and his name is Mammon. Nobody knows where he lives. At the end of 1888, a poor and unemployed man comes with his wife to his homeland. To the village of Rangville, which he once left with his mother as a child. He returns for profit to return his inheritance - the Sinister estate. But unfortunately, he could not achieve anything, because he seemed to be the illegitimate son of the landowner Lisitsyn. But he learns a terrible secret of his family, which allows him to enrich himself. He will have to meet the evil spirit of Mammon. But will he be able to resist him? After all, when you fall under the influence of a demon, you will no longer be a person; in addition to enrichment, he thereby corrupts the soul and dooms it to eternal torment in hell.
