Ruth is a minor who is running with an uptown, older man. Ruth's brother, Nick, is unaware of his kid sister's activities. Ruth is turned in to the juvenile authorities by the well-meaning Mrs. Humphries. Nick finds a man in their apartment and proceeds to be arrested for beating up the man, who runs away before Nick is arrested. Nick is taken to night court and remanded to the custody of the judge's niece, Janet, for six months as her chauffeur. Janet is the fiancé of Allen, who is coincidentally the man who was beaten up by Nick.
