Fidel Castro ruled Cuba longer than any other head of state in modern history, yet kept his private life sealed off from public view. This film builds a psychological profile of the man behind the revolutionary image, tracing how he experienced the key events of his career and what they reveal about his rigidity and force of will. Interviews include Natalia Revuelta, described as Castro's great love, their daughter Alina, former comrade-in-arms Huber Matos, Mikhail Gorbachev, Henry Kissinger, former German ambassador to Cuba Bernd Wulffen, Che Guevara friend Jean Ziegler, writer Norberto Fuentes, and Che Guevara's daughter Aleida. Together they sketch a figure seen by some as a symbol of political independence and endurance and by others as an example of ideological rigidity that never bent under criticism. The film treats Castro's personal history as inseparable from the wider history of the Cold War, using archival footage alongside these firsthand accounts to move between the private man and the public revolutionary.
