The Sentimental Lady(1915)

When he wasn't churning out "Curses, foiled again!" melodramas, playwright Owen Davis Sr. specialized in such social dramas as The Sentimental Lady. Irene Fenwick stars as Amy Cary, who has invested her life savings in a utility stock. Amy's fiance Norman Van Aulsten (John Davidson) is saddled with a crooked father (Thomas McGrath), whose Wall Street shenanigans threaten to wipe out Amy and the rest of the stockholders. Fortunately, crusading attorney Bob Nelson (Jack Devereaux) manages to prevent this financial catastrophe.
