Synopsis

Time: Whitsuntide or "Rusalka week", beginning of the 19th century

Place: Near the village of Dikanka, Ukraine

Act 1
Village street outside Hanna's hut; evening

The people sing a folksong-game. After they disperse, Levko plays the bandura and sings outside Hanna's window. When she steps outside, she's afraid that people will be watching them. After some endearing exchanges, she asks about the old house across the way, over the pond. He tells her that a widower used to live there; his daughter (Pannochka), lived with him, and he decided to marry again. The new stepmother turned out to be a witch, and caused the father to banish his daughter from the house. In sorrow she drowned herself in the pond and became leader of the other rusalki (drowned maidens). One night, while they were all dancing in the moonlight, they saw the witch walking by, grabbed her, and pulled her into the water. The story goes that, now, when someone comes by the pond, Pannochka asks the person to point out which of them is the stepmother.

The story over, Hanna goes inside, and some maidens come around singing a sad "rusalka" song. In stumbles the drunken Kalenik on his way home; he tries dance the hopak and to kiss the girls, but they send him away to the Mayor's house, tricking him into thinking that it's his own.

When all is clear, the Mayor sneaks in, calling for Hanna; from the side, Levko notices that someone is there, and watches. The Mayor, who has his eyes on marrying Hanna, tries to impress her with his oft-repeated story about being a guide for Catherine the Great, but Hanna rebuffs him, sends him off, and goes inside. Levko calls the village lads together and teaches them a song to mock the Mayor and use in playing a trick on him.

Act 2
Scene 1: Interior of the Mayor's hut; late evening

The Mayor and his sister-in-law are entertaining the Distiller at dinner. The Distiller will soon be tearing down the old house by the pond to build a distillery. Kalenik mistakenly bursts in and causes a mild disturbance; then a rock breaks through a window, causing the Mayor to curse the unseen perpetrator outside. In superstitious alarm the Distiller warns the Mayor against such language, relating the story of his late mother-in-law and the ghost that haunted her because of her cursing at him in life. Suddenly, outside, the village lads start singing the taunting song that Levko taught them. The wind blows out the lights, and in the commotion the Mayor captures someone he thinks is the perpetrator, and locks "him" up in a side room. The Clerk enters to report that the lads are running about the village and that he has captured their leader. The Mayor, in disbelief, calls for a light, and they open the locked room. Out comes the Sister-in-Law, sobbing and not a little enraged. She goes outside. The Clerk, the Distiller, and the Mayor set off to find the scoundrel once and for all.

Scene 2: Village street outside the Clerk's hut; moonlit night

Outside the Clerk's hut, where the alleged true perpetrator is locked up, the three approach in trepidation. Crossing themselves against Satan, they open the door, and again out comes the Sister-in-Law, infinitely more angry than before. Then the village police arrive, holding Kalenik mistakenly as prisoner. With the police afraid to proceed, the Mayor threatens them with the wrath of the commissar, and they run off in obedience.

Act 3
Shore of the lake near the old gentleman's house; luminous moonlit night

Beside the pond, Levko sings to his absent beloved, then asks the moon to shine its light on the path to her abode. A window opens in the old house, and Pannochka appears, begging Levko to sing further. He doesn't seem to notice her at first, but a strange feeling comes over him, and he sings again. Then the rusalki appear on the shore and dance. Overcoming his astonishment, Levko joins in singing their round-dance, while Pannochka begs Levko to find the stepmother-witch.

Then the rusalki begin to play the game called "Raven." The first raven-maiden finds that she cannot continue, and Levko realizes that she can't be the witch. But the second player of that role -- the stepmother -- exposes her true self; Levko points her out, and the other rusalki jump on her and drag her down to the depths of the pond. In gratitude, Pannochka gives Levko a letter to show to his father, and disappears as dawn breaks. Given that he cannot read, he does not know what the letter contains.

The Mayor and the policemen arrive and grab Levko. The Mayor is surprised to find that the disguised miscreant is his own son. Levko shows his father the letter, which is passed on to the Clerk to read out loud. The letter turns out to be from the commissar, and instructs the Mayor to allow his son to marry Hanna. As the villagers come on the scene to greet the new day, Levko invents the story that the commissar will be coming for dinner, and the Mayor, puffed up with his own importance, gives in to the marriage. Levko and Hanna say a prayer for Pannochka, Kalenik stumbles in again, and the Sister-in-Law gives the Mayor another verbal brow-beating, as the people celebrate.
