Etta of the Footlights(1914)

Etta Lang, a chorus girl, is the principal support of an invalid mother and her sister and brother, not only working at the theater, but looking after their small boarding house. Among their lodgers is Brutus Bellamy, an old actor. He becomes interested in the girl, and offers to teach her acting. She learns rapidly. She arrives at the theater late and is abused by the stage manager, Joseph Burton. Cecil Wentworth, one of the backers of the theater, takes her part and becomes interested in her.
