From the C.I.A. Archives, another "hands on" agent training film produced by the O.S.S. (Office of Strategic Services) during Word War 2 on the art of hiding (and finding) objects & secret information hidden in locations like homes, apartments, and hotel rooms. The story begins with an American industrialist working in a neutral country, who is working as an O.S.S operative. He has hidden a purloined chemical sample and other info in his apartment, which is soon searched by an enemy agent , who knows a few things, but doesn't know enough to find what he's after. The tables are then turned and the enemy agent's rooms are searched by O.S.S operatives, who do a much better job finding secret information. You'll learn a lot along the way, including how to set "traps" so you know your place has been searched, hiding & finding different kinds of objects and printed information, prioritizing & managing a thorough search, secret panels, doing a search so no one knows you've been there and much more.
