High-spirited hijinks at a haunted house. A titled, but financially strapped, gentleman opens up his Irish castle to American tourists in order to get some quick cash. Figuring that a haunted building will prove particularly appealing to the Yanks, he orders his employees to dress up and act like ghosts. But what the castle's owner doesn't realize is that there are a couple of real phantasms on premises -- and they've taken a liking to a bickering couple who have come for a visit.
