Mallory and Miller are back. It seems that there was traitor with them at Navarone, whom they thought was executed. But it seems that not only was he not executed, and he was not a traitor but a German spy. Intelligence believes he made it to Yugoslavia and is now with the Partisans. So, Mallory and Miller being the only ones who can positively identify him are sent along with a unit called Force 10, which is led by Colonel Barnsby, who objects to their presence. It seems that Force 10 has a mission of their own which Mallory and Miller know nothing about. When their plane is shot and most of the team is killed, they mistakenly believe that some of the locals they meet are Partisans but in reality are German Allies, so they are taken prisoner, and have to convince the German commander that they are not spies or else they will be killed.

On the run and hiding in the deep forests of the then German occupied Poland and Belorussia (World War II), the four Bielski brothers find the impossible task of foraging for food and weapons for their survival. They live, not only with the fear of discovery, contending with neighboring Soviet partisans and knowing whom to trust but also take the responsibility of looking after a large mass of fleeing Polish Jews from the German war machine. Women, men, children, the elderly and the young alike are all hiding in makeshift homes in the dark, cold and unforgiving forests in the darkest times of German occupied Eastern Europe.

The story follows an underground weapons manufacturer in Belgrade during WWII and evolves into fairly surreal situations. A black marketeer who smuggles the weapons to partisans doesn't mention to the workers that the war is over, and they keep producing. Years later, they break out of their underground "shelter" --- only to convince themselves that the war is still going on.

Christmas, 1983. A New York postal clerk, a Buffalo Soldier in Italy in World War II, shoots a stranger. In his apartment, police find a valuable Italian marble head, missing since the war. Flashbacks tell the story of four Black soldiers who cross Tuscany's Serchio River, dodging German and friendly fire. With a shell-shocked boy in tow, they reach the village of Colognora. Orders via radio tell them to capture a German soldier for questioning about a counteroffensive. In the village, a beautiful woman, partisans that include a traitor and a local legend, the boy, and the story of a recent massacre connect to the postal worker's anguish forty years later. And the miracle?
