In the middle of WWII, the German military was not especially enthused with the idea of tying up resources guarding troublesome POWs who kept wanting to escape. Now, to my mind, it would probably be more logical to separate all the troublesome prisoners from each other, but instead, the Germans decided to lump them all together in a special high-security POW camp. Probably not too surprising when you gather together dozens of escape artists, they end up orchestrating, well, a great escape. . . .
