When ex-cop Alexa Crowe (Lucy Lawless) returns to her New Zealand hometown, after years living in Australia, she's called upon to investigate puzzling murders by charismatic DI Harry Henare (Rawiri Jobe). Alexa is soon joined in Auckland by data analyst and partner-in-crime-solving, Madison (Ebony Vagulans), who's closer than ever to her mentor-literally, as she winds up living in Alexa's apartment. But to truly make a fresh start, Alexa must deal with the family troubles she's avoided for decades, starting with her wayward brother, Will (Martin Henderson).
