The Power of the Fiend

Dasha is saddened that her husband, Pyotr, is almost completely absent nowadays. His father, Il'ya, disgusted by Pyotr's sinful treatment of his family, prepares to move away. When Pyotr enters, he evades his father's questions of his whereabouts. After Il'ya goes off to attend vespers, Dasha tries to win back Pyotr's love, but he rejects her (he has become attracted to Grunya, the innkeeper's daughter) and leaves once again. Vasya—whom Dasha had once loved before marrying Pyotr—shows up to wish her a happy holiday. Taking advantage of his Shrovetide-induced, somewhat inebriated condition, Dasha learns from him about Pyotr's secret infatuation. She decides to move away from Moscow to live with her parents.

At Spiridonovna's busy inn, Yeryomka, and then Grunya, each sing a song for the visiting merchants and coachmen. As the others depart, Spiridonovna, desiring that her daughter marry someone well-off, urges Grunya to use her wiles on Pyotr the next time he comes in. When he does, she caresses him and manages to set up a date with him to go sleigh-riding that evening. He leaves, and Grunya overhears some people she does not know: Dasha's parents enter the inn, having come to Moscow to visit; Dasha, unexpectedly meeting them there, tells them of her decision. But her father forbids her to leave her husband and move in with them. From this conversation Grunya realizes that Pyotr has deceived her concerning his marital status.

Waiting to meet Pyotr at the inn, Grunya bemoans her fate. Upon arriving, Pyotr reads her change of mood as she spurns him, and guesses that only Vasya could have clued her in. When she goes off with Vasya, Yeryomka suggests to Pyotr that a visit to a witch-friend of his will solve his problems. Pyotr agrees to see her.

Out in the streets, Shrovetide merry-making is in full swing, with singing of songs and selling of food. Pyotr, drunk and brooding, comes upon the scene with Yeryomka. (The witch has told Pyotr that his future portends a wedding, hence his concern with being married still to Dasha.) When Vasya shows up with Grunya, Pyotr tries to kill him, but merely humiliates himself. After more Shrovetide revelers draw the crowd away, Pyotr comes once again under Yeryomka's influence: the latter proposes a plan: Dasha will be told that Pyotr has become ill out at the "wolf's gully." This conversation is overheard by Vasya, who runs off to warn her.

Out in the ravine, near a weakly lighted hut, amidst noises of a nocturnal snowstorm, Pyotr imagines voices of the previous few hours. Yeryomka enters, with Dasha, who has fallen for the ruse. When Pyotr rushes at Dasha with a knife, she runs into the hut; he follows her into it and kills her. The sound of approaching sleighbells frightens Yeryomka away: Vasya could not find Dasha to warn her, and so he, along with Il'ya and her parents, have driven to the site of the planned murder, only to come upon Pyotr, who is condemned by his father. (Note: in the original play, Pyotr gives up the idea of murder and reconciles his marriage.)
