Hollywood's Red Scare has been consistently represented as a nightmare of paranoia that victimized political innocents. But Ronald and Allis Radosh reveal the backstory behind this myth, taking us inside the discussion groups that Communist Party members formed, the unions they tried to take over, and the studios they aimed to influence. They show that many of the screenwriters who later became part of the Hollywood Ten in fact succeeded in using film as propaganda for the Soviet cause. When their CP allies abandoned them to face the HUAC investigations alone, they were left questioning their own loyalties.
