During the "Red Scare" of the 1950s, FBI agent and Slovenian-American Matt Cvetic (Frank Lovejoy) poses as a Communist to infiltrate the U.S. Communist Party. Unable to tell his friends and family about the undercover mission, Matt is deemed a traitor to his country and condemned by everyone close to him. Although Matt often doubts his dangerous task, he remains undercover to bring the Communists to justice and protect a faltering member (Dorothy Hart) from her vindictive party.
