Dana Andrews is undercover for Uncle Sam in I Was a Communist for the FBI. Based on the real-life exploits of Communist infiltrator Matt Cvetic, the syndicated series presented espionage dramas of Reds on the homefront and the efforts of the G-men to thwart their nefarious plans. Cvetic's story was adapted for the big screen in an Oscar-winning film and then on radio in this syndicated drama. We'll hear Matt Cvetic on the case in "Treason Comes in Cans."
