Summary: Instructional film for British military and civilian officials handling military, technical and scientific secrets, centering on an imaginary lecture at the Soviet School of Military Intelligence to Russian agents highlighting potentially vulnerable points of the "British Protective Security System". The students are taught on how to cultivate moles and agents from within the British Civil Service whilst stationed in the Russian Embassy in London.
Description: The lecturer addresses the British Protective Security System in place at that time (early 1960s), focusing on both the Personnel Security methods in addition to the Physical and Document Security methods. Includes insights into how the Russians allegedly viewed the British attitude and culture, footage of London rush hour, safe breaking techniques, key duplication methods, collecting and concealing documents, how to cultivate low grade personnel who may rise to sensative posts in later years and an enacted example of a British Civil Servant codenamed Leonid who was cultivated over several years.
