When bakery owner Lexy Baker and her posse of iPad-toting grandmas find a dead body under Ruth's late model Oldsmobile, it opens an investigation into a decades-old crime. It seems Ruth's reformed crime-boss boyfriend stashed something of immense value away before he died. Too bad word is out in the criminal underworld and a dangerous killer has come to town to find it. Armed with only their iPads, gigantic patent leather purses and a box of baked goods, the ladies must use their wit and cunning to unmask the killer before he hits too close to home.
