In 1987, Detectives Georgia Cooke and Michael Thorne investigate the grotesque murders of several scientists at Parrish Station, a remote astronomical research facility in the middle of the Australian desert. They find a lone survivor and a trail of bizarre clues. As Georgia digs deeper, she clashes with Callum Parrish, the research station’s powerful benefactor, and becomes consumed by this mystery.

Directed by Daniel Nettheim

In 2005, Georgia Cooke’s request to be released into the care of her daughter Frankie Cooke — now a recovering addict — creates a deep and lasting rupture between them. In 1987, Detective Georgia Cooke’s investigation into the Parrish Station killings takes her to a book called Llangnall Tower, which references a sinister text known as The Bone Gospel. But outside interference and a violent encounter with a missing scientist threaten to derail the case. By 2024, a strained reunion, a grotesque hostage ritual, and growing evidence that the copycat murders are linked to someone from the past bring the nightmare full circle.

Episode 3

Written by Yolanda Ramke
Directed by Daniel Nettheim

A cold open flashback reveals Detective Michael Thorne’s involvement in the Moorland shooting, where he shot an innocent boy. In 1987, Detective Georgia Cooke disobeys orders to question Kate Reynolds, who confirms The Bone Gospel is real and still at Parrish Station. As Georgia’s obsession deepens and her home life frays, Michael gives Callum Parrish secret access to Kate, to whom Callum gives a straight razor and an instruction to find her way back to him. Georgia makes a solitary trip back out to Parrish Station and is injured during a surreal and disturbing encounter.

In 2024, Georgia and Millie Farah continue investigating the copycat killings, leading them to Callum himself — an encounter that triggers Georgia’s PTSD. Shaken, she tells Millie she no longer wants to be involved in the case. Soon after, Millie discovers the mutilated body of podcaster Damien, posed like a victim from the Parrish Station killings, and shortly after, Georgia is abducted — by none other than Michael.

Episode 4

Written by Ben Jenkins
Directed by Daniel Nettheim

In a flashback to 2018, Michael Thorne remains under Callum Parrish’s control — defeated and directionless — until spotting The Bone Gospel sparks something long buried within him.

In 1987, Georgia Cooke is in hospital and told to drop the case as Kate Reynolds has been charged with murder. But when Millie Farah brings her a case file from 1950 — eerily similar to the Parrish Station killings — Georgia realises history is repeating itself. The woman involved in the 1950 case – Harriet Clay – was Callum’s mother.

In 2024, Georgia is revealed not to have been kidnapped but brought to a shed where Michael obsessively and showing signs of inebriation lays out his findings: the murders, the 37-year cycle, Callum’s role, Harriet as Callum’s birth mother, and the chilling belief that Kate Reynolds is still alive. As Millie juggles a new murder and a missing Georgia, she reunites with Georgia and Michael at the pub where they try to convince her and Elle Hardy of the connection between Kate and the present killings but uncomfortable truths surface. Back in 1987, Kate begins to miraculously heal before slashing Millie’s throat with the razor Callum gave her.

In the present, history echoes again — Millie steps outside for a cigarette and is abducted.

Episode 5

Written by Catherine Smyth-McMullen
Directed by Daniel Nettheim

In 1987, we see the killings at Parrish Station unfold as the five scientists begin to lose their grip on reality. Ray Tolliver exhibits strange changes after receiving a mysterious signal, while the others spiral into paranoia and violence after hearing a recording of it they weren’t prepared for. Surkov dies trying to escape. Kate Reynolds is forced to listen — then kills Paul Edgars in self-defence before destroying the recording.

Picking up from the end of Episode 4, Kate Reynolds vanishes from the hospital after slitting Millie Farah’s throat. Georgia Cooke tries to link the Parrish Station killings case with a similar case in the 50s, but it gets her suspended.

In 2024, following Millie’s abduction, Georgia, Michael Thorne and Elle Hardy are looking for Kate, whom they suspect is still alive, and uncover CCTV footage of a van that Georgia recognises. She realises Margaret O’Connor — Frankie’s assistant — may actually be Kate Reynolds.

Back in 1987, Frankie Cooke hints that “a man” is going to fix Kate. Desperate, Georgia takes her to confront Callum, where they stumble upon a cult-like ritual with Kate at its centre, her body riddled with holes again. Georgia snaps and shoots Callum. Frankie witnesses everything — just before Georgia is knocked unconscious.

And in 2024, Millie wakes bound in the desert, right where it all began… with a masked figure watching.

In 2019, all signs point to Margaret O’Connor being the missing Kate Reynolds, but the truth runs deeper and darker. In 2024, Georgia Cooke, Michael Thorne, and Elle Hardy track Margaret — only to find her dead and the real culprit revealed: Frankie Cooke/Webb. It’s revealed that Frankie, not Margaret, was the person Callum Parrish has been grooming as his new ‘vessel’ all along. Now a killer working alongside Callum to prepare for the ritual, Frankie has marked Millie Farah as the final copycat victim. When Georgia and Michael return to Parrish Station to stop them, they find more mayhem and Callum kills Michael. In a final act of defiance, Georgia deafens herself and turns the signal on Callum, destroying him. Frankie is saved but the deadly cycle created by the celestial signal appears to have begun anew…
