Retired lawyer Andy Carpenter remembers every dog that's come through the Tara Foundation's doors, but the most well-known alum of the dog rescue organization that Andy founded in Paterson, New Jersey, may be Mamie. Adopted by famous actress Jenny Nichols--Andy's high school girlfriend--the miniature French poodle is now practically a starlet in her own right.

Andy doesn't hold it against his friend. In fact, he and his wife, Laurie, have dinner with Jenny while she's in town filming her next big hit. But after an eventful meal, there's a plot twist the next morning that none of them see coming: Jenny's costar is found dead, a knife in his back. It's not long before Jenny is arrested for the murder and finds herself in need of Andy's legal services.

While Mamie becomes reacquainted with Tara, Andy's golden retriever, Andy digs into the lives of the rich and famous.
