Cupid Incognito.

Frank Graham, rich mine owner, is fatally injured by an explosion. On his death bed he confides to his friend, Jim Blake, all his plans concerning his daughter, Angela's, future. He makes him promise to watch over her. His fortune he places in the hands of his brother, a New York banker, to be held in trust for his daughter until her wedding day; the fact of her being an heiress to be kept secret in order to insure her safety from fortune-hunters.
