Intended for military personnel and civilians in sensitive positions abroad, the film shows three playlets involving foreign agents maneuvering Americans into passing valuable intelligence to the Soviets or Red Chinese. It emphasizes the need to be wary of seemingly friendly strangers, whether one is in Europe or Japan.
