In this slow-paced thriller set just before D-Day in Paris, Gus Lang (Ed Harris) is an American agent who has to make sure a captured U.S. officer is not forced to divulge the secret of the Normandy invasion. Since audiences know the invasion worked, the success of Gus Lang's espionage forays into Nazi officialdom, and the French resistance appears to be a foregone conclusion. At least Paris provides an excellent backdrop for his undercover work, both with the attractive Claire Jouvet (Cyrielle Claire) and the less-attractive Nazi military.
