In the quaint town of Sea Harbor, Massachusetts, Nell Endicott and the other Seaside Knitters are helping Gracie Santos open the Lazy Lobster and Soup Café on Pelican Pier. They take a break to enjoy a yacht club dinner honoring, among others, Gracie's aunt and uncle, Sophia and Alphonso. Then, by the light of the full moon, the members of a local scuba club witness a red Ferrari flying off a cliff to the rocks below -- with Sophia Santos behind the wheel.
