A fearless fortune teller in 1920s Paris must use her powers to divine who she can trust when an exiled Romanov princess and her brother come to her seeking answers about a decades-old mystery.

Spirited Zina and her secretive 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, mostly to members of the bustling Russian émigré community, 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, eager to learn more about the spirit world and her powers, performs the séance. She is able to summon the Grand Duke, but to her horror, he starts to haunt the shop, and he 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.
