It's 1933, the golden era of aviation. The Pathfinder is an 800-foot passenger zeppelin. It is the pinnacle of human invention; the largest thing to fly. It has just been hijacked. A band of modern-day pirates have seized control via fighter planes and poison gas. With the passengers and crew hostage, the pirates are flying the Pathfinder into the heart of South America on a deadly mission. But among the passengers is a man to be reckoned with. He is Nathan Carter, a mercenary and ace pilot with nothing to lose. After a failed attempt to liberate the Pathfinder, Carter must flee, along with a beautiful pickpocket and a couple of determined crewmen. Escape only lands them in the middle of a South American war, in which the Pathfinder shall soon play a terrifying role. From the Iguazu Falls of Brazil, to the blood-soaked battlefields of the Chaco War, and to the thrilling climax high above the Andes Mountains, Carter and his friends must take the fight back to the pirates.
