This drama-documentary tells the tale of 10,000 German Prisoners of War, who were held in three stately homes rigged with recording devices. Little did they know there was a covert British intelligence operation underway, to record all of their conversations. Sure wouldn't they say anything when they thought they were among friends? Prepare yourself for a few horrors as the previously classified reminiscences and confessions are read by a cast of actors including Nicholas Farrell, Rupert Frazer and Peter Harding.
