Arabic rights to Dar al-Kutub
1778. The Urals are smoky by mining plants. And for factories there is only one road to Russia – the rough river Chusovaya. But here the barks with factory iron are ruthlessly destroyed by coastal rocks. For the rafters, who lead the barks on the river stremnins, there is a way to avoid the wreckage: to ask Satan for help, and transfer their immortal soul to a schismatic sect. However, the young raftingman Ostash raises a revolt against the sect. The reason, it seems, is in the gold of the Pugachev treasure hidden somewhere on the rocks.
