The friends dive into their own investigation with the help of Joy's daughter Kate soon crossing paths with DI Simon Lund. As old crimes surface and dark patterns emerge, the group of friends finds that this seemingly idyllic resort town – with its beach walks, pub lunches, and good-natured bickering - hides something far more sinister. Together they must piece together one devastating mystery and track down a killer who has been hunting in this close–knit coastal community and beyond.
