Directed by Anatole Litvak

Film Synopsis

Warsaw, 1942.  After a woman's dead body is found, Major Grau, the head of the military police sets about finding her killer.  From a witness he learns that the murder was a German officer, and this provides Grau with three possible suspects: Tanz, Kahlenberg and Von Seydlitz-Gabler.  Before he can conclude his investigation, Grau is suddenly transferred to Paris.  Two years later, in the immediate aftermath of the Allied invasion of France, Grau is unexpectedly confronted with the three generals he had previously had within his sights.

His interest in the case re-awakened, Grau teams up with a French police inspector, Morand, who has obtained secret documents revealing Kahlenberg's involvement in a plan against Hitler - a plan that Von Seydlitz-Gabler was evidently aware of.  Tanz proves to be the most suspicious of the three generals.  One night, he murders a prostitute and contrives to inculpate an innocent man.  Convinced that Tanz is the man he is after, Grau arrests him, just before the news comes through on the radio that the plot against Hitler has failed...
