Detective Kate Farrer returns to duty after three months of leave following her traumatic abduction. Fearing that she has lost her edge, she reluctantly partners homicide newcomer Oliver Parke, and they are thrown into the investigation of a woman burnt beyond recognition in a house fire. The post-mortem reveals she had recently given birth, but there is no sign of the baby. With homicide short-staffed, Kate and Oliver are also ordered to look into the disappearance of a teenage girl. Suspicion falls on Mark Dobbie, a steroid user who is obsessed with the missing girl's sister. When the detectives find explicit photos of unconscious women in his home, they wonder if they have found their prime suspect. While the pressure to identify the charred body and find the teenage girl escalates, a quadriplegic is burnt to death in his bed. Shocking links to all three crimes emerge and Kate Farrer's past demons come back to haunt her. But she must fight them - for her partner's life depends on it.
