Spying and subterfuge in occupied Paris from one of the great masters of the spy genre.

Inspired by the true story of Polish prisoners in Nazi Germany, who smuggled valuable intelligence to the French resistance.

Occupied Paris in 1942, a dark, treacherous city now ruled by the German security services, where French resistance networks are working secretly to defeat Hitler.

Just before he dies, a man being chased by the Gestapo hands off to Paul Ricard a strange looking drawing. It looks like a part for a military weapon; Ricard realizes it must be an important document smuggled out of Germany to aid the resistance.

As Ricard is drawn deeper and deeper into the French resistance network, his increasingly dangerous assignments lead him to travel to Germany, along the underground safe houses of the resistance - all the way to the mysterious and beautiful Leila, a professional spy.
