Bill Snibson, a chancer from Lambeth Walk in South London, is informed that he has been discovered to be the long-lost heir to a title and castle which he can claim provided he is able to convince his new relations that he has enough aristocratic bearing. Things soon begin to go awry however, particularly when Sally, Bill's girlfriend from Lambeth, turns up.
