The Bay is set in the coastal town of Morecambe Bay and centers on Detective Sergeant Lisa Armstrong who is assigned to a missing persons investigation in the unique village. At first it seems like any other tragic, but all too familiar case, and as a police Family Liaison Officer, Armstrong is trained never to get emotionally involved. But there’s something very different about this particular case when she realizes she has a personal connection to the frightened family – one that could compromise her and the investigation.
