An American's story of courage and struggle to liberate Cuba. A tough ex-military man and sniper, William Morgan left the United States in 1957 to join guerrillas in the mountains of Cuba. Leading groups of fighters, he, Che Guevara, and others advanced across the country until they managed to force the corrupt dictator Fulgencio Batista to surrender power. However, upon assuming power, Fidel Castro canceled the elections, confiscated properties, and imprisoned fellow soldiers, including Morgan. In the midst of a passionate romance with the beautiful and determined rebel Olga Rodríguez, whom he later married, the two decided to oppose the new government, attempting to retake it from Fidel and Che. Based on Olga's diaries and information released by the FBI, CIA, and U.S. Army intelligence, Pulitzer Prize winners Michael Sallah and Mitch Weiss reveal the inner workings of the Cuban Revolution while presenting the love between a woman dedicated to her country and an ordinary American hero who left his mark on history.
