CineCalidad. This film is based on the classic novel of the same name by writer Ivan Franko, one of the most famous figures of Ukrainian literature. It is set during the 1200s and the invasion of the medieval Ukrainian-Russian state of Rus' by Chengis Khan's Golden Horde. Due to its having been produced during the Soviet era, the story's aspect of class-conflict between the "heroic" peasantry and the "decadent" noble particularly emphasized here.
