Charles le Temeraire asks in marriage Jeanne de Beauvais, daughter of King Louis XI, wishing to get her valuable lands in dowry. The King is wise to this, and since his daughter does not feel inclined to accept, he refuses. Charles sets up a plan to abduct the prince, in a way that the suspicions will fall upon Robert de Neuville, a noble enamoured of the princess. Robert manages to free her from the castle where she was being kept. Charles keeps setting traps, and managing people to perjure against Jeanne, and the King himself. Finally, Jeanne escapes alive from a pack of wolves, who set watching the lady alone in the snow covered woods, instead of attacking her. Charles does yet accuse her of being a witch - wishing to have her dead rather than being the wife of Robert... Robert will be her champion in a Judgement of God. Will the 'miracle of the wolfs' repeat itself, or fearless Charles defeat Robert in the sword duel?

This is the second part of a projected three-part epic biopic of Russian Czar Ivan Grozny, undertaken by Soviet film-maker Sergei Eisenstein at the behest of Josef Stalin. Production of the epic was stopped before the third part could be filmed, due to producer dissatisfaction with Eisenstein's introducing forbidden experimental filming techniques into the material, more evident in this part than the first part. As it was, this second part was banned from showings until after the deaths of both Eisenstein and Stalin, and a change of attitude by the subsequent heads of the Soviet government. In this part, as Ivan the Terrible attempts to consolidate his power by establishing a personal army, his political rivals, the Russian boyars, plot to assassinate him.
