Mysteries of Paris

Directed by Jacques de Baroncelli

With Marcel Herrand, Yolande Laffon, Alexandre Rignault, Lucien Coëdel and Roland Toutain

Paris, 1830. Fleur de Marie is rescued from poverty by the mysterious Rodolphe, who is in fact the Grand Duke of Gérolstein, who has gone incognito in search of an illegitimate child he once had. Which is not at all to the taste of Sarah Mac Gregor, her current mistress who kidnaps Fleur and has her locked up in Saint-Lazare prison.
