French Legionnaire Battron parachutes into Sicily to lay the groundwork for the allies invasion of Italy during WWII ! July, 1943. In preparation for the British-American invasion of Sicily, Battron parachutes onto the island with a mixed group of Allied intelligence operators. Led by his old comrade Captain Bryan Watson-Cole (SOE), and a young Lt. Robert Beck (OSS) who has family relations within the Italian population, and underworld connections stretching back to the New York Mafia.

The team is on Sicily to observe and report on German troop and supply movements to the frontlines. But by seeking the aid of the local underworld, they may have put themselves up for sale to the Germans. When the invasion finally comes, and the wheels of battle begin to turn in earnest, Battron and his team go about their job of professionally observing and reporting German movements down a major mountain road.

But when one of their team commits a single innocent discretion, the whole mission is thrown into turmoil, which could cause the death of hundreds, maybe thousands, and even hamper the outcome of the invasion.
