As the last true witches living in a city shifting from magic to industry, Marlinchen and her two sisters are little more than tourist traps as they treat their clients with archaic remedies and beguile them with nostalgic charm. Marlinchen spends her days divining secrets in exchange for rubles and trying to placate their tyrannical, xenophobic wizard father, who keeps his daughters sequestered from the outside world. While at night, she and her sisters sneak out to enjoy the city's amenities and revel in its thrills, particularly the recently established ballet theatre, where Marlinchen meets a dancer who quickly captures her heart. But as Marlinchen's late-night trysts grow more fervent and frequent, so does the threat of her father's rage and magic.
