Peter Benton arrives in Buenos Aires, Argentina in June 1945 to investigate possible fraud in the local office of a foreign film distributor. In Buenos Aires, he reunites with his partner from his days in the OSS, who has been posted to the U.S. embassy. His friend recruits him to spy on the most powerful figure in Argentina, Colonel Juan Pern, and his young mistress, Eva Duarte. Complicating the assignment is the simultaneous arrival of a former Germany army officer who is on a secret mission to deliver gold to Pern that will help pave the way for the re-birth of the Third Reich. Benton soon finds himself caught up in a dangerous game of high-stakes diplomacy, political intrigure, deceit, and betrayal, a game that not only puts his own life in danger but one that threatens the life of the young Argentine beauty with whom he falls in love. This story of suspense and romance is told against the realistic backdrop of a major turning point in the history of Argentina and its relations with the United States.
