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.

Lye edited together “swing” versions of the popular Lambeth Walk (including Django Reinhardt on guitar and Stephane Grapelli on violin), combining them with a particularly diverse range of direct film images, scratched as well as painted. He was particularly pleased with a final guitar solo (with a vibrating horizontal line) and double bass solo (with a stomping vertical line). For this film Lye did not have to include any advertising slogans; friends at the Tourist and Industrial Development Association, shocked to learn that Lye and his family had become destitute, arranged for TIDA to sponsor the film – to the horror of government bureaucrats who could not understand why a popular dance was being treated as a tourist attraction. - Harvard Film Archive
