Synopsis by Hal Erickson
When her father goes broke, Irish colleen Betty (Bessie Love) is forced to sell her ancestral home. But rather than part with the domicile completely, Betty stays on as a housemaid, while her dad is hidden away in one of the darker wings of the building. Thanks to papa's drunken nocturnal wanderings, everyone assumes that the house is haunted, but this does not faze the aristocratic new owner Roger O'Reilly (Frank Borzage) in the least. Nor is Roger dissuaded from his efforts to win Betty's hand in marriage, despite her socially unacceptable "pauper" status. Everything turns out all right in the end when it is discovered that Betty is actually Lady Betty -- a "revelation" tipped off from the outset by the title of the film.
