In a Paris suburb nicknamed Little Jerusalem, a family of Sephardic Orthodox immigrants shares a low-income apartment. Beautiful, teenaged Laura (Fanny Valette) distances herself from her family's religion and her own burgeoning desire by devoting every waking moment to intellectual discipline and secular philosophy. Mathilde (Elsa Zylberstein, That Day), Laura's married older sister, worries that strict observance of the Torah's marital codes has driven her husband Ariel (Bruno Todeschini, Code Unknown) into the bed of another. When Laura falls under the spell of Djamel, a handsome Muslim Journalist, and Mathilde discovers that her worst fears are true, the two very different sisters find themselves in very similar crises.
