Attending a swanky cookie exchange is the last thing on veterinarian Dr. Mandy Brown's holiday to-do list, but she agrees to help a friend out. The party comes to a screeching halt after a body turns up on the kitchen floor, a carving knife jutting out of his back. As if that wasn't bad enough, Mandy comes face-to-face with Officer Dylan Shaw, a man she thought she was dating until he ghosted her. Tensions escalate as motives for murder come out of the pantry as fast as guests scarf down the pot-spiked brownies, making everything all the merrier. Although the case seems open and shut, Mandy doesn't believe the evidence. Can she and Dylan put their differences aside and find the real killer, or risk one of the bakers getting away with murder?
