Welcome to beautiful Blue Lake. Nestled peacefully in the Adirondack Mountains, it’s the kind of place where nothing bad ever happens - until now. Summertime in Blue Lake Village. Celia Strong arrives with her daughter Katie to start a new life as the owner of Ye Olde Ice Cream Shoppe, leaving personal tragedy and her old life as a NYPD forensics expert behind. As Celia settles in, she bonds with fellow year-rounders, like eccentrics Helen and Henry from the antiques store, unflappable Lorna Lucas at the history museum, fun-loving Richard and Daniel from the art gallery, and, of course, the distractingly handsome Cal at the country diner. It's just a typical Friday when a tourist bus pulls up in town with seven passengers on board, one of them dead. The six remaining passengers each hide a secret. Is one of them the killer? As connections among the riders emerge, acting Sheriff Denny DeWalt turns to Celia - with the help of the rest of 'the block' - to solve the case.
