About the title
The bogatyrs are expecting additions to their families, but the fatherland once again needs saving. A huge cloud has appeared out of nowhere, threatening to blot out the whole world and turn day into night. Setting aside family matters, the bogatyrs rush to face the danger. And the cunning merchant Kolyvan seems to have been waiting for exactly this — having recruited villains from Baba Yaga's henchmen as his helpers, he attacks the principality. But it's not all smooth sailing for him. The bogatyrs go to help the Prince, the city, and their faithful horse Julius.
