After her divorce from her thrice-married embezzler husband, Trinidad Jones is finally ready for a fresh start. So when she's left one of her ex's businesses in Upper Sprocket, Oregon, she decides to pack up her dog, cash in her settlement, and open her dream business: the Shimmy and Shake Shop, introducing the world to her monster milkshakes. And even with a couple sticky situations underway, namely that the other two ex-wives also call Sprocket home, Trinidad's life seems to be churning along smoothly.

That is, it was until she discovered her neighbor, the Popcorn King, face down in his giant popcorn kettle. When one of Trinidad's fellow ex-wives is accused of the murder and Upper Sprocket descends into mayhem, it's going to take a supersized scoop of courage to flush out the killer.
