A year on from her husband's death, new detective Ember Manning is called to an arson attack. The investigation that follows brings Ember into contact with an underage pregnant girl, who Ember suspects has been seeing an older man. When a true crime podcaster, in town to investigate a cold missing persons case, tells Ember that the older man is actually a serial predator, Ember finds herself reflecting upon the age difference between her and her late husband.
Still reeling from her shocking discovery, Ember is desperate to find out what Riz knows about the Amy Knightly case. They begin to share information and Ember tells Riz her suspicions about the identity of Miranda's abuser. Ember is horrified when she's told that the lake is to be searched for Amy's remains. When Riz stops returning Ember's calls, Ember suspects that it's because she has uncovered the terrible truth about what happened to Amy.
Ember knows it will be only a matter of time before the police find the incriminating voicemails. With the police focusing on the body, Ember is determined to find out who Miranda's abuser is, hoping this leads her to the killer. Learning the truth about who has been abusing Miranda, and the inevitability that Mack was likely responsible for Amy's disappearance, pushes Ember to breaking point. And when Hannah's safety is threatened, Ember soon realises she has nowhere left to turn.
Suspended from duty and with Mack's anniversary celebration looming, Ember is forced to confess to her family that human bone fragments were found in the boat hut. Devastated, Hannah can't believe her dad was responsible and pleads with Ember to look further. Ember's instincts tell her this isn't a done deal. Doubling down, Ember is determined to finally get to the truth of what really happened to Amy. When a shocking new development propels Ember into dangerous territory, the truth is finally revealed, and it's far more shocking than she ever expected.
