Insurance salesman Tom and his wife Jenny are struggling through the first years of marriage in a modest flat, on Tom's even more modest salary. By contrast Drew, Tom's old army pal, is a footloose bachelor currently running a car-hire firm owned by his rich uncle, who lives in Canada. Since Drew's uncle makes it clear that his nephew will only inherit the business when he's a respectable married man, his upcoming visit throws Drew into a panic. Having taken a fancy to the vivacious Jenny, Drew persuades her to masquerade as his wife – an arrangement that leads the trio into some highly complicated situations!
Jean and Bill are a married couple trying to scrape a living. Out of the blue they receive a telegram informing them Bill'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.
