When jewelry-store owner Gina Gallo and her boyfriend Pete take a week's vacation, she leaves the store in the hands of her cousin from New York. After all, cousin Carmine is a certified gemologist, but Carmine is also in the Mob. When Gina gets back, she discovers that her cousin has spent his time switching real gems for fakes in the jewelry of some of her best customers. With her reputation on the line, what's a Mob goddaughter to do? Mastermind a string of burglaries to get the gems back, of course! But nothing ever goes entirely smoothly for Gina. Soon she and her eccentric cousin Nico are the toast of the town, as the local paper and everyone else follow the antics of their very own Pink Panthers.
