When veterinary technician Carrie Kennersly has a chance to buy a local bakery, she jumps at the chance and converts half of it into the Barkery, a shop where she can make and sell canine delights. Myra Ethman, co-owner of another pet product store, hates the new competition, and at the Barkery's opening party she badmouths Carrie's homemade dog biscuits, insisting she'll find a way to shut the place down. When Myra is found dead with a Barkery biscuit beside her, Carrie must prove she didn't do it before she's collared for murder.
