Black Sheep of Whitehall

The Harrow Correspondence College - Principal, Professor William Davis - differs from its more notable namesake in more than one respect, and in no greater respect than size. It possesses only one pupil, and he hasn't paid his fees. When Professor Davis visits the pupil, a young assistant in the press division of the Ministry of International Commerce, in an effort to extract the unpaid fee from him, he becomes involved in a hilarious series of misadventures with kidnapped professors and Nazi plots, and culminating in a crazy car chase involving a baby carriage and a bath chair.
