Engrossed in his business affairs, John Kirby fails to assess the seriousness of his wife Helen's objections to the constant parade of business chums and their mistresses who come to dinner. When Kirby gives Helen the ultimatum of accepting the status quo or filing for divorce, she divorces him and obtains a position as a stenographer in the office of one of her husband's friends, but leaves after he makes advances toward her. Finding employment as a model in a dress shop, Helen is invited by one of the girls to attend a masquerade ball with two gentlemen friends. Helen agrees and discovers that her escort is her ex-husband. Although he cannot identify Helen because they are masked, Kirby suspects that his date is his ex-wife and arranges for another meeting in which he asks Helen to remarry him, and she agrees to make him her second husband.
