After a long hot summer in Balsam Dell, Carly Hale is ready for crisp Vermont weather and gourmet grilled cheeses at her Grilled Cheese Eatery. And the upcoming Halloween food competition is the perfect way to impress the locals. But Ferris Menard, the owner of Sub-a-Dub-Sub, is nursing a serious grudge against Carly. Two days before the competition, one of Carly's employees quit his part-time gig at Menard's sub shop, sending Menard into a serious snit. In a confrontation at the Eatery, Menard accused Carly of sabotage and vowed to bring her down. That's when Menard's body is found in his kitchen the morning after the competition, a steak knife sticking out of his heart. But Menard had a slew of enemies, and if Carly doesn't figure out which one is the culprit, she might find herself—or someone she cares about—serving grilled cheese sandwiches under lock and brie!
