Hearts and Masks (1921)

Alice, an energetic vixen, lives in a country estate with her gouty uncle, who denies her any companions. She plagues him with pranks until he leaves the estate. Now free to seek adventure, she dresses as a maid and convinces a passer-by, Richard Comstock, a celebrated author, that the estate is a boardinghouse. She has the servants pose as distinguished guests. The uncle returns and spoils the spoof. Later she meets Richard at the hunt club ball, which Galloping Dick, a gentleman burglar, also attends, in a strictly professional capacity. When jewels are discovered missing, Alice, thinking Richard is the thief, hides him in the cellar, where they run into Galloping Dick's accomplice. Alice and Richard are at first denounced as thieves, but the actual culprits are apprehended.
