Things get under way when Blondie Bumstead demands that her husband request a raise from his boss Mr. Dithers, so that she can afford to hire a maid. But Dithers has no time for any salary disputes: his construction firm is currently stuck with an unsaleable old mansion that is rumored to be haunted. To disprove this theory, Dithers asks the Bumstead family to spend a night in the crumbling old house, throwing a retinue of servants into the bargain.
