Prisoner of War plot
"THE NAKED TRUTH ABOUT LIFE IN THE P.O.W. CAMPS! (original print ad - all caps)"
A US military officer, troubled by reports of his brutality, volunteers to check living conditions in the North Korean wartime prison camps. He is dropped behind enemy lines and infiltrates a group of GIs who have just been transferred to one of these camps. There he witnesses brainwashing, systematic beatings, fake executions, days without food and water and a long list of torture supervised by a Russian colonel. While the response to these "treatments" has met with varying degrees of success, the Russian officer learns that despite everything, the American soldiers still turn out to be a brave and close-knit group of friends.
