In four episodes, we witness how Satan (Nissen), accursed by God, must walk the Earth and tempt men to do evil; he can only hope to be delivered from his curse if someone resists him, but few do.
Episode 1 tells the story of the betrayal of Jesus by Judas, enticed by Satan in the guise of a pharisee.
Episode 2 takes place in 16th-century Spain; Satan is a grand inquisitor, who manipulates a young, tormented monk into comitting an ugly rape.
Episode 3 takes place during the French Revolution; a young man who has the opportunity to save Marie Antoinette from the guillotine allows her to be executed, because she reminds him of a misdeed he was tempted to commit by Satan, now a Jacobin leader.
Episode 4 is set during the Finnish civil war in 1918. Here, Satan is a defrocked monk leading a bolshevik rabble. He threatens to kill the family of Siri, a telegraph operator, if she does not send a message luring the Whites into an ambush, but she resists and kills herself rather than turn traitor.
