Grégoire Duval (Bernard Blier), one of the most upstanding citizens in his provincial French town, commits a spur-of-the-moment crime of passion and subsequently gets picked for the jury when a man with a dubious past goes on trial for the murder. Grégoire's probing questions get the man acquitted but in the eyes of the community, the defendant's still a killer and when Grégoire eventually confesses to the crime, nobody wants to hear it...
Director Georges Lautner's extremely satisfying film noir also doubles as an autopsy of cold, cruel, hypocritical bourgeois values and is not unlike "Madame Bovary" in that respect. The philosophically resigned voice-over narration of a man tormented not only by what he's done but by the way his entire life played out has a chilling effect and it's a dark universe, indeed, right down to THE INVASION OF THE BODY SNATCHERS ending (on Christmas Eve, no less). There's bitter irony to spare with a dazed walk through nocturnal city streets present in some of the finest noir such as ELEVATOR TO THE GALLOWS and BLAST OF SILENCE and director Georges Lautner (who'd go on to make the giallo-esque ROAD TO SALINA with Rita Hayworth & Mimsy Farmer) gives the bleak proceedings a grey, misty patina that doesn't go away, even in the daytime. The Francis Didelot novel the film is based on was adapted in the U.S. a year earlier for an episode of THE ALFRED HITCHCOCK HOUR called "The Star Juror" and the timeless tale was also turned into a 2008 TV movie in it's native France. 10/10!
