A future of happiness awaits San Francisco shipping executive Brad Collins (Robert Ryan) and his new bride (Laraine Day).Yet Brad's past could undo everything. Back in his days as a dockworker, he was an activist member of the Communist Party. Now the Party has resurfaced like a bad dream in Brad's life, putting the screws on and threatening to spill his past if he doesn't play ball and stir up a labor strike. In an era when some officials sought to weed out Communists real and imagined, Hollywood made numerous films that exploited the times. Among them: Big Jim McLain, Invasion USA, I Was a Communist for the FBI and this film ' arguably the most hyperbolic of all ' originally titled I Married a Communist.
