June 6, 1944. On the dawn of the D-Day invasion of Normandy, two snipers find themselves fighting a battle all their own. One is a backwoods hunter from the Appalachian Mountains in the American South, while the other is the dreaded German "Ghost Sniper" who earned his nickname on the Eastern Front. Locked in a deadly duel across the hedgerow country of France, the hunter matches wits and tactics against the marksman, both of them one bullet away from victory or defeat as Allied forces struggle to gain a foothold in Europe.

It's 1942. America have just joined the war. Greyhound, an international convoy of 37 allied ships, is in operation. As Captain Ernest Krause leads his first command of a US destroyer, the convoy ploughs through icy, submarine-infested North Atlantic seas. All the while hotly pursued by wolf packs of Nazi U-boats. Grappling with his newfound superiority and haunting self-doubt in 48 hours of desperate peril, Captain Krause's hopeless mission is doomed to fail. But armed with extraordinary courage and grit, hope may just be on the horizon.

December 1944. As German forces launch a massive surprise attack through the frozen Ardennes Forest, two snipers find themselves aiming for a rematch. Caje Cole is a backwoods hunter from the Appalachian Mountains of the American South, while Kurt Von Stenger is the deadly German "Ghost Sniper". Having been in each other's crosshairs before, they fight a final duel during Germany's desperate attempt to turn the tide of war in what will come to be known as the Battle of the Bulge. Can the hunter defeat the marksman?

WWII sniper Caje Cole embarks on a rescue mission behind the new Iron Curtain for American POWs held as political pawns by Russian forces. To free them, he will have to defeat his deadliest adversary yet, the Red Sniper. The brutal Russian believes that he can outgun anyone, but he hasn't met the likes of this backwoods hunter and marksman. 

Autumn 1944. With the Allies giving chase across France, German forces are in full retreat after the defeat at the Falaise Gap. Now, two of these orphaned squads - one American unit, one German - find themselves in a small French village with a bridge across that river. Both sides want possession of the ancient bridge across the Moselle, and the result will be an epic showdown that pits general against general, and sniper against sniper.

While the politicians on both sides negotiate, the armies in the field are fighting a brutal war of attrition across the rugged Korean Peninsula. Sniper Caje Cole and his squad have one clear objective, which is to capture the next hill and keep it from falling back into enemy hands. That’s not easy when the enemy still attacks in overwhelming numbers. At the Battle of Triangle Hill, the soldiers find themselves in a stalemate with Chinese forces, fighting to capture and then regain a strategic foothold. 

Bataan has fallen to the Japanese. The Philippines seem sure to follow. When a general surrenders the last American outpost in the West Pacific, Navy Lieutenant Todd Ingram refuses to give up the fight. Taking to sea under cover of darkness, he leads his ten man crew to accomplish the impossible: Slip through Japanese naval blockades, travel 1900 miles to Australia, and singlehandedly stop a ruthless Nazi spy.

It is 1942. Lt. Harry Gilmour has already made a name for himself in the Royal Navy submarine service. He has risked his life to save a fellow seaman after his first boat, HMS Pelorus is rammed and sunk in the North Sea. He’s played a leading role in HMS Trebuchet’s epic foray into a fjord in the then-neutral Soviet Union to scatter German ships secretly assembling to invade Iceland. And as number three on HMS Umbrage in the Mediterranean, he had assumed command after her skipper had been lost overboard and gone on to attack an Italian cruiser squadron.

Juan de Santiago is not only a billionaire coca grower, he is also a deranged revolutionary; the commander of the most powerful private army in South America. Backed by power-hungry rogue nations who supply him with the latest weaponry, de Santiago devises a plan that will dishearten the American antidrug effort and make him El Jefe once and for all.

As 1941 draws to a close, brave young men are fighting for freedom in countries across the globe. But for Sub-Lieutenant Harry Gilmour, washed up in neutral Spain alongside 'interned belligerents' from both sides of the war, hostilities have come to a pause. Before long, his unlikely comrades must once again become his enemies, and he is back at the frontline of the battle for the Mediterranean.
