The murder of a prostitute and German Agent in Nazi occupied Warsaw draws Wehrmacht Major Grau (Omar Sharif) into an investigation where the evidence points to one of three high ranking Generals. The trail leads Grau from Warsaw to Paris and into conflict with the 1944 plot to assassinate Adolf Hitler, of which two of the Generals are involved. Grau's case goes unresolved, and it is not until 1965 when the true killer is brought to justice.—Anthony Hughes
