Aly, Azzedine, Nadir, and Sophiane are friends who spend time in a park in the 18th arrondissement of Paris on a street called Rue des Cloÿs. They communicate with each other through the universal languages of soccer and a collaborative form of slang called Verlan and Argot. The movie uses playful animations to illustrate the transformation of traditional words into Verlan and Argot words. The protagonists are of immigrant descent and belong to a demographic that is sometimes stereotyped as being violent and criminal. In “Les Cloÿs,” they tell their own stories with their own words.
