Ida Rappaport, senior citizen and baker extraordinaire, is asked for baking lessons by Lily and Kitty, her new Chinese twin neighbors. She happily complies, and soon discovers her best cookie recipe book has disappeared. The twins, one of whom is recently married to a man on assignment in the U.S., confess they need money for return tickets to their native Hong Kong as Lily's marriage is not working out. Ida soon learns the new bakers have started a baking company in their apartment, and tenants complain of late night baking odors wafting through their windows. The Tenants Association president, who has been romantically spurned by Kitty, organizes a petition for building management to investigate a possibly illegal business. The Good Fortune bakers outmaneuver the inspector but another disaster strikes. Their American baking career ends but is reborn in Hong Kong.
