Dana Osborne is looking forward to some quiet time after going undercover with a rock band to solve her last case. But she's forced into action when an old friend starts to receive mysterious threats, and Detective Wade McNeish once again proves about as much use as a custard guitar pick.

Dana, her assistant Brody, and guitar shop cat Paws McCartney, are thrown into a world of dodgy corner stores, illegal distilleries, and - scariest of all - a community ukulele group. To save their skin, they need to figure out who is the killer, and fast!
