Food critic Hayley Snow and her pal Miss Gloria are overjoyed to welcome Violet and Bettina Booth, aka the Scottish Scone Sisters, to Key West. The sisters will host The UK Bakes!—Key West Edition. But the same day they arrive, the bed-and-breakfast the sisters are staying in gets torched. The contest begins the next morning featuring three local bakers. One is the inn owner’s wife, Rayna, who is not only the most talented chef of the group but now a person of interest in the fire. The next night, a dogwalker discovers a body near the bed-and-breakfast. The victim appears to be Rayna’s husband, and the murder weapon points directly to the Scottish Scone Sisters. But the show must go on. In between filming sessions, the three elderly ladies and Hayley must search for clues to the brutal murder in order to find out who wants to force them out of the kitchen. But as they draw closer to the answer, the threats from a murderer grow closer too. Are they now in danger of getting baked off?
