Tunisia, 1930s. Against the backdrop of a country in turmoil, in search of its identity, the lives and destinies of the members of two important upper-class families of Tunis intertwine: the Ennaifer family, with a rigidly conservative and patriarchal mentality, and the Rassaa, open-minded and progressive.

One terrible night in December 1935, the destiny of both families changes forever when Zbaida Ali Rassaa, the young wife of Mohsen Ennaifer, is accused of having had a clandestine love affair with Tahar Haddad, an intellectual of humble origins known for his union activism and support for women's rights. The events of that fateful night are told by eleven different narrators, members of the two families, who recall them in different historical moments, from the 1940s to the present day. The result is a complex mosaic of secrets, memories, accusations, regrets, and emotions, taking the reader on an exciting journey through the stories of individuals caught up in the upheavals of history.
