Granny leads a secret life in the small, unique community of Fuschia, Minnesota. It's not just her all junk food diet, multiplying pets, or her shocking bedtime attire that makes Granny one in a million. No, Granny is an undercover cop, charged by "the Big Guy" (the town's police chief) of preventing theft in local stores. Granny takes her job seriously and daily foils many shoplifters using her trusty spiked umbrella and amazing acting skills. When some startlingly brazen burglaries begin to occur that Granny can't solve, along with mysteriously appearing bad guys, disappearing clerks, and misplaced Corvettes, Granny begins to wonder if she isn't ready for the wrinkle farm. Maybe, it's fortuitous when she accidentally-on-purpose falls in the lap of an attractive older gentleman who is soon roped into her wild adventures, as they try to figure out what's happening in their little town.
