When Devon, a mix of MacGyver and Sheldon, crash lands in Nazi-occupied France, his urgent mission becomes not one of escape, but one of rescue-to find his brother who may still be alive after bailing from an American bomber just moments before. On this hero's journey, he is sidetracked by a young woman, Claire, who trades her knowledge of France for Devon's help in recovering her father, arrested as a suspected member of the French Resistance. A relentless adversary pursues them at every turn. All the while, Devon carries with him the burden of a terrible secret that could destroy any hope he has of enlisting the help he needs in finding his brother-a secret that could also crush any chance he has at winning Claire's heart. An escape from the gates of the notorious Fresnes Prison, and a wander candlelit through the formidable maze of the French Catacombs, takes them into the very belly of the Nazi Luftwaffe beast. They must find a way to work together to stay one step ahead of capture, and return Devon's brother back to the safe shores of Britain.
