Jean and Matt Spenser are trying to scrape a living. Out of the blue, they receive a telegram informing them Matt's long-lost uncle has died and left them his business—a cinema in the town of Sloughborough. Unfortunately, they can't sell it for the fortune they hoped as they discover it is falling down and almost worthless.
