When a dog walker stumbles upon a dismembered limb in Delamere Forest, the city of Liverpool is thrust into a nightmare. As Detective Chief Inspector Olivia Mann spearheads the investigation, her team uncovers a series of grotesque murders, each echoing the tragic stories of vulnerable young women: runaways from the care system and workers lost in the city’s red-light district. As the body count rises, the detectives discover unsettling symbols carved into the flesh of each victim, suggesting a methodical, ritualistic killer who is targeting society’s most marginalised.

Adding to the chaos, Liverpool reels from the shocking stabbings of three teenagers on a school bus—an incident linked to rampant drug-related violence and a growing knife crime epidemic. As pressure mounts from the media and the community demands justice, Olivia finds herself caught in a perilous balancing act. The clock is ticking, and resources are stretched thin.

With each new victim, the investigation deepens—leading Olivia into the dark underbelly of Liverpool’s criminal world, where she must confront a powerful OCG whose empire may be interwoven with the killer's sinister agenda. As the threads of both cases intertwine, Olivia’s resolve is tested. She must navigate a treacherous landscape of betrayal and fear, racing against time to unmask a predator before more lives are lost.

In Zodiac, secrets are buried deep, and the truth is more chilling than anyone could imagine. Olivia must confront her demons and the darkness that lurks in the forest and within the very fabric of the society she vows to protect.
