Idylls before the war turn into a nest of wasps and intrigue. James Mason is the innocent medical student on a vacation from his studies in Paris, who gets his camera 'borrowed' by someone who takes some forbidden pictures of the French navy at Toulon - just before the war. Naturally James Mason gets implicated for the heinous crime with prison, expulsion and perhaps execution to look forward to as a sudden interruption of his medical career, which was not what he had expected of his holiday in Provence by the delightful Mediterranean with some lovely young ladies around at the ideal hotel. Among the guests are a German citizen from Berlin who proves himself to be a direct victim of the Gestapo, a fugitive from Prague and a former social-democrat journalist with nothing good to expect from his Gestapo pursuers, and he is the tragedy of the case. The hotel and its environment is very much like in the comedy "French Without Tears", it's the same atmosphere and the same idyllic charm, which is brutally contrasted by sinister proceedings. Several of the guests are great comedians. James Mason makes the best of a precarious predicament, sometimes loses his temper at the risk of his life, and he is absurdly compromised, but that is all part of the game. The French police know what they are doing, and the only thing missing here is Hercule Poirot.
