He'll do anything to save her ... even work for the enemy.
August, 1944. In German-occupied Paris, former schoolteacher Auguste Duchene has stumbled upon an unusual way to survive: he finds missing people. When he's approached by the French Resistance to locate a missing priest - and a cache of stolen weapons - Duchene initially refuses. But the Resistance offer him no choice. Within hours, he's also blackmailed by a powerful Nazi into searching for a German soldier who's suspected of deserting.

So begins a frantic race against time. As forces close in on Paris, Duchene has only 48 hours to locate the missing priest and soldier, or lose the only person he loves...
