“Each of you is an ambassador, and we are sure that each of you will be the best ambassador of our country.” This is how the film begins; a speech to emigrant workers for France. Salah left his three sisters and his mother to become an ambassador, going to work on a Defense site, wading in the mud, he works with a jackhammer. Salah wanders in search of work and housing. Coming up against racism from the owners claiming the respectability of the building and the good neighborhood, he finds himself in a hotel in the Goutte d'Or district. The body of Mehdi, friend of Salah, was found in the Canal Saint-Martin, murdered by a fascist commando, and Ali died of a bullet, killed by a racist janitor. Faced with crimes that remain unpunished, Salah and his friends organize, unite with the French working class to defend their lives and their right to work.
