A dream or two ago (1916)

During a jewelry-store holdup, 6-year-old Millicent Hawthorne, the neglected daughter of a wealthy socialite, falls on her head and is carried home to be reared by Mother Gumpf, the leader of the thieves. The fall cost Millicent her memory, but at night she dreams of her former high-society existence, while during the day she works for Gumpf as a pickpocket and later becomes a cabaret dancer. A friend of the Hawthornes sees Millicent perform, recognizes her, and reports back to Mrs. Hawthorne, who has vowed to be a devoted mother should she ever find her daughter. Finally, after the Hawthornes rescue Millicent from Kraft, the lecherous cabaret manager, an operation restores her memory, and she delights in the love of her long-lost mother.
