Mary Beresford is the devoted and self-sacrificing wife of a man whose ambition is great, but whose energy in achieving that ambition is less than nothing. He has a fairly responsible place with a well-known firm and holds it solely because his wife does most of his work for him after hours in their home. One day a particularly important stack of papers is given to Al Beresford by his employer; a report must be in the hands of their most distinguished client that night. Al dawdles through the day and at night takes the unfinished job home. He and Mary start to work it out together, but he pleads a headache and goes to bed. She finishes the work and delivers the papers in person to Elihu Jasper. Jasper is a powerful operator in Wall Street and lives alone in a big mansion. He is attracted to Mary and in an effort to help her summons Al to an interview. He soon finds that the man is unworthy of consideration, but because of the woman he gives Al many tips that increase his income and enable the Beresfords to move into palatial quarters. Jasper is a frequent visitor there, bored by the man's egotism, but secretly admiring the woman. There comes a day when Beresford is convinced that his rise is due entirely to his own efforts, he regards the wife who has made his position possible as a hindrance and urges her to give him his freedom. A widow in society has attracted him. Mary departs and the world swallows her up. Jasper is informed of the situation by her maid. His mind quickly formulates a plan. Al Beresford is wiped out in the street and commits suicide. Then comes the long hunt for Mary, but not until Jasper goes into the market to thwart a plot to deprive him of a profitable mine does he discover her as the secretary of his broker. He saves the mine and wins the woman.
