Ulusal Deniz ve Balıkçılık Hizmetleri'nde çalışan bir görevli kıyıya vuran bir ceset bulur. Polisler kendisini davanın yakınında istemeseler bile cinayeti çözmeye kararlı bir şekilde araştırmaya koyulur.
"Hightown" is set on iconic Cape Cod, and it follows one woman's journey to sobriety, intertwined with an unfolding murder investigation. Jackie Quiñones, a hard-partying National Marine Fisheries Service agent, has her free-wheeling life thrown into disarray when she discovers a body on the beach - another casualty of Cape Cod's opioid epidemic. As a result of this trauma, Jackie takes the first steps toward becoming sober - until she becomes convinced that it's up to her to solve the murder. Now at odds with Sergeant Ray Abruzzo, an abrasive but effective member of the Cape Cod Interagency Narcotics Unit, Jackie starts to spiral. And she's not alone. Ray, too, spins out of control; losing himself in the investigation. The lives of everyone connected to this murder crash and converge, reminding us just how complicated - and deadly - our addictions can be.
