Amelia, a wealthy young socialite, is in her boudoir getting ready for the first ball of the season. However, her husband has discovered that she has a lover and refuses to accompany Amelia unless she reveals his name. When she reveals that her lover is their upstairs neighbour, a general melee breaks out between the jealous husband and her pesty lover, with Amelia eventually breaking a vase over her husband's head. When the police arrive, she tells them that a burglar had entered the apartment and attacked her husband with the vase. Her husband is taken to hospital, her lover is arrested as the burglar, and Amelia leaves for the ball on the arm of the Chief of Police who has come to investigate.
