The spoiled son of an indulgent father gives up his home and career after a quarrel and leaves home. He drifts down the path of life with vice and degradation as his companions. He meets a girl in a saloon whose life has always been in the depths and falls in love with her. This girl meets a sister of charity, who tells her of "The Light About the Throne," and urges her to reform, giving her a card and telling her to call on her at any time she needs help.
