October 1942. At a secret rendezvous point off the coast of neutral Argentina, a small merchant ship delivers supplies to Nazi submarines and raiders. The OSS is determined to sabotage the operation by any means necessary. But one of the key saboteurs they've enlisted - a yound U.S. Marine - must fight his own private battle between duty and honor. Because he was chosen for a reason - to gain the trust and support of his own flesh and blood. A powerful Argentinian called 'el Coronel.' The father he never knew.
