Paris, 1928. Maryse Choisy is an eccentric figure of the literary and journalistic world: she was a novelist, journalist, poet, psychoanalyst, philosopher, occultist, orientalist, and a mystic. Commissioned by a publisher, she decided to become the first woman reporter to infiltrate the world of Parisian prostitution. Far away from her well to do family roots and academic environment, first disguised as a prostitute, she somewhat panics when a customer approaches her, so she finds a job as a maid in a brothel, and from there, like an undercover agent, she emphatically observes the women in their daily occupations, winning their trust and taking notes in the evening for her future book. From the bordello to underworld balls, and a lesbian bar where she will dance, she’s a forerunner of “immersive“ journalism aiming to describe these women and their condition. During her inquest, she sharpens her judgment and demystification is total. Brothels debase women, and turn them into objects at the service of customers looking to cure their neurosis, annihilating all hopes of wedlock. Twenty years ahead of her time, she came to the conclusion that they must be closed. From this experience was born Un Mois chez les Filles (A Month with the Girls),” the boldest and oddest experiment that a woman has ever dared to live and write about”, (says her publisher), an immediate success, selling over 100 000 copies. It provoked a scandal that continued even after she had the book removed from book stores in 1939. With era archives and reenactments played by Nine d’Urso and Jeanne Balibar, the provocative journalist shares her avant-garde report on the much fantasized Paris of the roaring twenties. Audrey Gordon invites us into a first person documentary fiction, a confession, an intimate diary that follows the rhythm of Marion Choisy’s book, and depicts a path towards a truth that now seems clear, but was at the time, heroic.
