This one-off documentary explores the secretive and strange arms race between Britain and the Nazis during WW2.
Convinced that the path to victory lay in out gunning the Nazis but faced with limited resources, British weapon manufactures were forced to improvise.
To combat the problem, Winston Churchill himself set-up a secret clandestine research institute, dedicated to coming up with super weapons that would give troops the edge in battle. He christened the department Military Defence 1 but it quickly becomes known as Churchill's toyshop.
Using rare archive and interviews, the one-off special tells the story of the department and some of the most fantastic and improbable weapons ever created. With the help of modern experts and contemporary blue prints the series will also recreate some of the lost technology.
