A passenger car carrying a reporter and his photographer mysteriously breaks away from their train, accidentally ending up on a side track in Gudavia, an isolated Ruritanian-style one-village Eastern Bloc dictatorship. The newsmen find a mad scientist using gamma rays to turn the country's youth into either geniuses or subhumans at the bidding of an equally mad dictator.
