It was quite recent time when France had another bout of hate for Jews. Searching for a spy in the military the investigators stumbled upon a Jewish officer and didn’t need to look any further. He was promptly sentenced, but then the proofs of the mistake started coming up. Acknowledging it would put even more people in quite bad light, so everyone doubled down. Except a truly exceptional officer, even though he wasn’t a good marriage material. It’s an entertaining movie about real piece of history.
