The Great St. Trinian's Train Robbery

"Alphonse" Askett (Frankie Howerd) is a hairdresser who is also the operational leader of a gang of crooks who are led behind the scenes by an invisible mastermind (voiced by Stratford Johns). He gives instructions to Askett about the robbery, Operation Windfall, using a variety of James Bond-like communications devices—including a converted showerhead.
