Forced to work nights, a young Austrian bureaucrat is unable to escort his lovely wife to a masquerade ball. Unbeknownst to our hero, his wife and her maid slip off to the ball on their own. Wifey makes the acquaintance of her husband's best friend who, unaware of her identity, is quite smitten by her and invites himself to her home. She manages to get rid of her lovesick swain by removing her mask and gown and disguising the maid as herself. Never revealing her true identity, the maid enjoys a passionate evening in her escort's apartment. The next day, the husband, who hasn't a clue as to what has transpired the night before, invites his friend home to "meet the missus." The friend is naturally terrified at the prospect that the wife will reveal their romantic rendezvous of the night before, little realizing that he'd actually spent the entire evening with the maid. How this situation eventually straightens itself out is far better seen than described.
