Paris, February 1944: 23 resistance fighters, most of them foreigners with Communist leanings, are sentenced to death. Ten days after they have been executed, their photos stare out from posters plastered in the city's streets, to denounce what the government calls "an army of crime against France: the famous Red Poster."
Organized in armed groups, in 1943 the resistance fighters carried out several spectacular actions: identifying targets, collecting weapons, acts of sabotage. They did every and anything they could to bring down the Nazi occupiers. Unfolding like an investigative documentary, the film offers a historical reconstruction of the hunt for the resistance fighters, mixing judicial and police archives as well as archives from resistance movement members.
