Se encuentra en la playa el cuerpo del entrenador local del club de fútbol Trent Latham. La sargento Dulcie Collins se hace cargo, pero el Det. Eddie Redcliffe llega para hacerse cargo de la investigación, causando fricciones.
In an effort to link a previously unsolved death, Dulcie exhumes former mayor's body and raises ire of the community. The boat of Sam O'Dwyer, who disappeared years ago, is set on fire, while Eddie chases a hooded figure through the bush.
As the Deadloch Feastival program continues despite two murders, the body of another suspect is found on the shore of the lake. Despite the victim being dead for five years, Dulcie suspects that it's linked.
While Dulcie and Cath's relationship hits a very rough patch, new suspects are named and dismissed, but it's Eddie's slip up at a press conference that really makes an impact
In the aftermath of Eddie's press conference, Deadloch is in a state of panic and the killer strikes again; taking the count up to five. Eddie and Dulcie jump from suspect to suspect as relationships crumble around them.
When the most compelling suspect ends up being a close friend of Dulcie's - it creates conflict in multiple relationships. Meanwhile the evidence is piling up, and more bodies are emerging.
The killer's spree continues and with all the town's men in danger. Commissioner Hastings is chasing the wrong lead. Dulcie, Eddie, Sven and Abby continue to investigate the murders in secret, and they finally work out who the killer is.
