In the six-part drama, Eric Bana stars as a federal agent who works for the National Parks Service. He is tasked with investigating the unusual death of a young woman in Yosemite National Park. In particular, how she ended up falling off El Capitan mountain.

There is so much packed in to its half dozen episodes, it would be no surprise if some fans missed a detail or two by the finale. This includes what happened to Lucy and who she really was, along with what really happened to Caleb and the true reason Agent Turner's marriage fell apart.

Here's all you need to know about the biggest moments from Untamed's finale:

Who killed Lucy Cook in Untamed and who was her real father?

The history of Lucy Cook is just as important in Untamed as what happened to her. She lived with her mother Maggie, until her death from cancer. Lucy was still a child when her mother died so was left in the care of her father. Or rather, who people believed was her father at the time.

He was violent and abusive and so Lucy was taken away and left at a foster home in Nevada. At the time, it was thought Lucy went missing and many presumed her father killer her. He died in a bar fight three years later.

The person who whisked her away is revealed to be her real father, Paul Souter, played by Sam Neill, who had an affair with Lucy's mother and kept it secret for decades.

Unfortunately, the foster home was also a place full of abuse and Lucy eventually escaped. She returned to the park where she apparently extorted her real father for money, before getting herself mixed up in the drug trade taking place within the park.

Wanting to put an end to the blackmail he was suffering, Paul chased Lucy down one night. Firing off what he intended as a warning shot, he hit her in the leg. She ran away from him, but died from her injuries before falling off El Capitan.

After Paul admits what he did , he still cannot bear the thought of the truth being revealed to his wife and children. He takes his gun and turns it on himself.

What happened to Caleb in Untamed?

During the investigation into Lucy's death it quickly becomes clear that Agent Turner is set to be confronted by his past. Little by little, viewers discover that this is related to the fate of his own child, his only son Caleb.

It is also linked to the case of a missing person: Sean Sanderson. Turner and his wife have always known what happened to Sanderson.

He is the man who abducted and murdered Caleb in the park. They discovered this thanks to cameras set up by wildlife maintenance officer Shane Maguire. Instead of handing this information to authorities, for some reason Turner's wife Jill hires Maguire to kill Sanderson.

She did this without the knowledge of her husband. After he found out, their marriage quickly broke apart.

Maguire seemed to initially believe he would get away with his role in the drug ring because of the information he held over Turner and his wife. However, Turner still attempts to arrest him in an altercation which quickly turns violent and results in Vasquez shooting Maguire dead.

What were the screaming heard in Untamed's last episode?

The series, in a similar way to another hit crime drama show True Detective, leans into the idea of the supernatural. That becomes clearly apparent when it is revealed that Turner keeps seeing and speaking to the spirit of his young son.

He believes that Caleb is still present in the park and at more than one point he contemplates joining him on the other side. Near the end of series, muffled screams can be heard as Turner looks out over the water. This will be more obvious if you're someone who watches with the subtitles switched on.

Turner's friend Jay warns him that a 'Wuyi' might come up from the water and snatch him. He adds that the 'little ghost' doesn't take anyone unless they want to be taken before asking if Turner has heard his screams.

Where does Agent Kyle Turner go at the end of Untamed?

Bana's Turner is a changed man by the end of the series. At the beginning, he is contemplating if he can even go on living, but is somehow compelled to see the latest investigation through.

By the end, he is now ready to say goodbye to parts of the past that haunts him. However, he no longer feels like he is abandoning the spirit or positive memories of his son and is able to finally leave Yosemite for good, acknowledging that Caleb will always be with him.

He is still suspended from his job, so at this point in time we can only assume he is not travelling to be positioned at a different National Park. Perhaps instead he is having to relocate to somewhere he is less comfortable, like a bigger city, mirroring the change made by Naya Vasquez.

Untamed is streaming on Netflix.
