Are you ready for a delicious Mother's Day treat? Pie shop owner Bertha Hannah might not have any children of her own, but this Mother's Day she is celebrating by helping to cater a Wine and Cheese party for some of the richest ladies—and mothers—in all of Culver's Hood, Nebraska. She has a delicious cheesecake tart prepared for the occasion, and things start off swimmingly, until a gruesome discovery is made at the elegant venue. When the hostess of the party is found, face down, in one of the estate's beautiful fountains, Detective Harry Manor is all too ready to point a finger at one of Bert's fellow church members, who happens to be at the party. Bert steps in, along with her friends Shiv and Carla, to see what clues they can find to exonerate the innocent churchgoer, before the real killer slips through their fingers and gets away with murder.
