Dalton Trumbo’s career as a screenwriter blossoms just as FBI director J. Edgar Hoover makes Hollywood his focus for rooting out communism. Trumbo becomes active in the Screen Writers Guild, a harbour for radical politics. Charlie Chaplin makes influential friends on the political left. With his first talking film, The Great Dictator, Chaplin draws critical praise and unwanted attention with a rousing speech. Shifting alliances between Soviets and Nazis force an awkward political reckoning in the US. Host Oona Chaplin explores the FBI's covert operations which targeted alleged communists. We learn how Hollywood became the battleground for the soul of America.
