In this French comedy, the young adult children of working-class Arab immigrants living in the projects of suburban Paris endeavor to find a suitable cultural identity. The story centers on four young men in their 20s: Farida, who tries to live according to family traditions; his rebellious sister Souad, who wants to be as Westernized as possible and works at a fast-food outlet; her ex-boyfriend, Jean Luc, who wants to be an immigrant lawyer; and his friend Moussa. The film is comprised of brief incidents from their lives.

Hexagone, shot in the Parisian suburb of Goussainville, documents the life of a working-class banlieue through a fragmented, episodic narrative which interweaves the lives of a variety of characters, principally drawn from the Maghrebi community.
