When two fishermen find the body of a local farmer in the river, Detective Inspector Mike Shepherd is sent to the small rural town of Brokenwood to investigate the death. Is this the suicide of a man guilty of his own wife's murder or is he the victim of foul play? As Mike uncovers a family's tragedies and secrets he also learns that Brokenwood is a place where shadows lurk just beneath the surface.

A group of erstwhile members of the Brokenwood Golf Club, committee members no less, have gathered for their regular Wednesday morning round. They are playing their approaches to the first green when a zombie-like figure lurches from the early-morning gloom, coming towards them. It takes the golfers a moment or two (apparently) to realise this is actually Adele Stone, the Club owner - her face red and blistering; gasping desperately for breath. Then she falls from sight, into a greenside bunker. By the time the guys get to her, Ms Stone is very much dead. And so Mike and Kristin are called to investigate what appears to be homicide by poisoning.
