Film from the series Polish Tales and Fables, season 1 (based on the legend of Wielkopolska 'O Macieku Borkowicu i diable Boruta'). A certain mayor leads a life of debauchery and plunder. He makes his own rules within his own territory. He feels only respect for Wojtek, a member of the Blacksmith family, who helps everyone, advises everyone, and, most importantly, imprisons the local devils, imps, and imps of all kinds in a willow tree. The mayor avoids encounters with the blacksmith as much as possible. Since he's constantly short on gold, he makes a pact with the devil Boruta. However, he reneges on the terms of the agreement, and the devil seeks the blacksmith's help. Together, they concoct a ruse. The mayor is thrown into prison. The blacksmith frees all the devils—on the condition, of course, that they never return to the area.
