Mystery shopper Josie Marcus catches a new case when the owner of a popular doggy day spa bites the dust and her mother's friend is collared for the crime… Josie's been assigned to sniff around Uncle Bob's Doggy Day Camp, one of St. Louis's hottest pet spas. It doesn't take her long to dig up dirt on the camp's top dog, "Uncle" Bob Manning himself. Employee Frank Hyzy—Josie's mom's new boyfriend—reveals Bob should be in the doghouse for his cruel treatment of the canine customers. But before Josie can write Bob up, someone puts him down…and Frank is the cops' prime suspect. While Frank definitely had a bone to pick with the animal abuser, Josie doesn't believe he murdered Bob. So she must doggedly pursue the investigation on her own and hope she can cage the real killer before they fetch another victim.
