Zina and her grandmother, Baba Valya, own a tearoom on rue Daru in Paris, where they have lived quietly since Zina’s mother’s untimely death. By day, the women serve tea. But when dusk falls, they divine fortunes and perform séances for their loyal clientele. Then the charming Princess Olga and her brother arrive, searching for knowledge about the disappearance of their father, the exiled Grand Duke, cousin of the last Tsar of Russia. Zina performs the séance and is able to summon the Grand Duke. But to her horror, he starts to haunt the shop and seems to know something sinister about her mother’s death. As Zina delves into her family’s hidden past, dark secrets are unearthed, threatening the home and tearoom Zina and her grandmother have worked so hard to build, not to mention their very lives.

It is the summer of 1921, and a group of Bolsheviks have taken over Irina and Lili Goliteva’s ancestral home in Moscow. The remaining members of their family are ordered to move into the cramped attic, while the officials take over an entire wing of grand rooms downstairs. The sisters know they must forget their noble upbringing to make their way in this new Soviet Russia. But the house begins to whisper of a traumatic past not as dead as they thought. Eager to escape it and their unwelcome new landlords, Irina and Lili find jobs with the recently arrived American Relief Administration. But at home, the spirits of their deceased family awaken, desperate to impart what really happened to them during the Revolution. Soon one of the officials living in the house is found dead. Was his death caused by something supernatural, or by someone all too human?
