Wealthy stockbroker Lemuel Morewood wants his sons, Billy and Tom, to learn the business and marry Emily Donelson and Frances Berkeley, respectively. Billy, however, is infatuated with Mrs. Bruce Guilford, a leader of the "smart set," while Tom loves boxing. At a dinner for which Lemuel hires Bessie Brayton, an orphan from the West, to entertain, Lemuel responds to Bessie's taunts about being old-fashioned by winning a lot of money gambling with Major Bellamy Didsworth, who tries to swindle Bessie, and leaves with her to spend it.
