Marseille, March 1941
Four years have passed since Tom Lancaster returned to Europe and he is now living a double life as Alphonse Prideux, an unremarkable church maintenance man, in the unoccupied zone of France. Together with Emilie, his married girlfriend, and her sister, he forms part of a local resistance network that prints anti-fascist newspapers and helps some of the thousands of refugees that have flooded Marseille since the invasion. One night, at a night-club where Emilie is singing, he is approached by a man from the French secret service and blackmailed into killing a German agent. To give his network a chance to disappear, he agrees, but events take a strange turn, and before long, he is forced to flee the country together with a woman he doesn't know. Meanwhile, in Paris, Emilie, a famous singer, puts her faith in her abusive husband and manager, Gerard. Reluctantly she spends her time entertaining the occupying Germans, both for her career and for the chance to get some useful information. With most of her friends having left Paris as the Germans came marching in, she feels alone and vulnerable and longs for the days when she sang in smaller clubs, to people that mattered to her. With a Paris unaware of where her loyalties lie, she becomes a target for citizens believing her to be a collaborator. Her husband sees the Nazis as a great business opportunity, and in the end, will he be the one who betrays her? What none of them realise, is that they are all playing their parts in a game. A game controlled by the Germans, a game that could win the war and lose them their lives.
