John Morgan, a model husband, in order to promote a business contract with Henry Carter, drinks heavily and goes to an artists' ball with a redheaded girl, hoping to conceal the escapade from his wife, Angela. Through an acquaintance with Mrs. Williams, the "lady-friend" of Henry, Angela learns of her husband's scheme; and donning a red wig, she goes as his escort to the ball. The arrival of Carter's jealous wife leads to numerous amusing complications. When Angela learns the purpose of his deceit, she manages affairs so that Morgan succeeds in getting the contract but keeps her identity secret.
