We Are All Murderers

René Le Guen (Marcel Mouloudji) is a former resistance fighter trained as a young man as a professional killer. After World War II, he has no qualms in applying these skills and is arrested for murder. Convicted and condemned to death, he is held in a prison cell with other murderers sentenced to death. Men to be guillotined are taken out at night, so they wait in fear and only sleep after dawn. While Le Guen's lawyer (Claude Laydu) tries to achieve a pardon for his client, three of Le Guen's fellow inmates are executed, one by one, in the course of the film.
