Blue-Eyed Mary(1918)

When her son has married beneath the family, Mrs. Van Twiller Du Bois disowns him and decides to leave her fortune to her nephew, Cecil Harrington. She does, however, agree to educate her granddaughter Mary, who comes to live with Mrs. Du Bois in hopes of reconciling her father and the old woman. Cecil, actually a local robber whose identity has just been discovered by the police, plans to rob his aunt and leave town. Just as he is emptying the safe, Mary enters the room, and when Mrs. Du Bois comes in, Cecil tries to blame Mary for the robbery. The police soon arrive to clear Mary's name and arrest Cecil, and Mrs. Du Bois is reconciled to her family.
