We follow the everyday travails of a group of WW2 French resistance fighters in Marseille, including their engineer leader and a middle-aged woman who sets up anti-German attacks without telling her husband or daughter, as they do battle against the occupying Nazis, collaborators and traitors in their own camp. This tense and atmospheric classic, based partly on Joseph Kessel's novel and partly on Melville's own experiences as a resistance fighter who later escaped France to join the Free French forces and who was hence ideal to make this film which, as well as being an ode to the resistance, has all the trappings of a great gangster movie.
