The Lamb and the Lion (1919)

A girl known as "Boots," who keeps house for a band of crooks led by her kind guardian, Uncle Ben, called "The Lion," demands that she be allowed to accompany them on a burglary. Dressed in boy's clothes, Boots is caught by Mrs. Kathryn Sylvester, a rich society widow, who, upon learning that Boots is a girl, resolves to avenge herself on James Graham, who refused to marry her stating that he wanted no stain on his lineage. She raises Boots in luxury, and at the proper time, introduces her to Graham's son Donald. After Boots endures an awkward two years of study during which she still frolics with her pet pig, she and Donald fall in love. During their wedding, Mrs. Sylvester announces Boot's past to Graham, but Uncle Ben, now reformed, reveals that Boots is really the daughter of Major Richard Harvey, who is present. The happy couple then resume their wedding.
