The series opens with two climbers scaling El Capitan in Yosemite National Park when a dead woman, Lucy Cook, falls past them, attached to their climbing rope. The authorities find a bullet lodged in her leg, indicating her death was not accidental. This discovery triggers an investigation led by Special Agent Kyle Turner, a seasoned but troubled investigator haunted by the murder of his own child years earlier. Turner teams up with rookie ranger Naya Vasquez to uncover the truth behind Lucy's death.

Turner's personal life is strained; he is estranged from his ex-wife Jill, who is also grappling with their shared trauma. Jill has moved on with another man, which fuels tension when Michael, Jill's current partner, confronts Turner at his home. The confrontation escalates until Turner intervenes and detains Michael. Jill, overwhelmed by jealousy and emotional pain, attempts suicide using pills she obtained from Shane Maguire, the park's wildlife management officer.

Turner visits Jill in the hospital and then confronts Maguire at a hotel, physically assaulting him over Jill's suicide attempt. This public outburst leads to Turner's suspension from the investigation. While handing over his case materials to the FBI, Turner discovers a phone among Lucy's belongings. He uses a method involving formaldehyde on Lucy's corpse to bypass the phone's facial recognition and unlock it.

Inside the phone, Turner finds videos revealing that "Terces" (the word "secret" spelled backward), Lucy's anonymous lover, is actually Shane Maguire. The videos show Shane abusing Lucy and reveal his involvement in a drug trafficking operation using old mining tunnels in Yosemite. Turner confronts Maguire at his camp, armed and prepared. During the confrontation, Maguire shoots Turner with a rifle, leading to a tense chase through the wilderness. Eventually, Vasquez arrives and shoots Maguire, saving Turner's life.

Despite Shane's violent behavior and criminal activities, Turner concludes that Shane is not responsible for Lucy's death. Further investigation reveals that Lucy's biological father is Paul Souter, the chief park ranger and Turner's mentor, not Rory, who had been believed to be her father. Turner confronts Souter, who admits to having an affair that resulted in Lucy's birth. Souter confesses that he placed Lucy in a foster home in Nevada, unaware that the family was abusive.

Lucy returned to Yosemite as an adult and began blackmailing Souter for money. In a confrontation intended to scare her, Souter accidentally shot Lucy, which led to her falling to her death off El Capitan. This revelation shocks Turner deeply. Before Turner can report Souter, Souter pulls out a gun and commits suicide.

The series closes with Turner processing the painful truth about Lucy's death and his mentor's role in it, while also dealing with his own fractured family and the emotional scars left by past tragedies. The investigation exposes a web of abuse, secrets, and crime hidden beneath the surface of Yosemite National Park.

The ending of Untamed season 1 reveals that Lucy Cook's death was indirectly caused by Paul Souter, the chief park ranger, who shot her in an attempt to scare her due to her blackmailing him. Shane Maguire, initially suspected and involved in a drug trafficking cover-up, is killed in a shootout with rookie ranger Naya Vasquez. Kyle Turner, the main investigator, resolves the case but feels emotionally unburdened and directionless, leading him to resign and pass his badge and horse to Naya, symbolizing a new beginning.

Expanded narrative of the ending scene by scene:

The final episode opens with Kyle Turner discovering a video on Lucy Cook's phone showing Shane Maguire, a reclusive park ranger with a military background, interacting with her. This discovery leads Kyle to confront Shane at his remote camp in Yosemite. Shane is found with a pill bottle marked with an X, the same symbol tattooed on Lucy's arm and linked to a drug trafficking ring operating within the park. As Kyle holds the bottle, Shane shoots him in the stomach, initiating a tense shootout through the rugged mountain terrain.

Despite Kyle's injury and bleeding, Shane pursues him relentlessly. Just as Shane is about to kill Kyle, rookie ranger Naya Vasquez arrives unexpectedly and shoots Shane, ending the immediate threat. This moment marks a critical turning point, showcasing Naya's bravery and skill, and positioning her as a potential successor to Kyle.

Meanwhile, the deeper truth about Lucy's death unfolds. Kyle learns through DNA testing that Lucy's biological father is not Rory, as believed, but Paul Souter, the chief park ranger and Kyle's mentor. Paul admits to having had an affair with Lucy's mother and placing Lucy in a foster home, unaware of the abuse she suffered there. When Lucy returned to the park and began blackmailing Paul for money, he shot her in an attempt to intimidate her, which unintentionally led to her death.

Another major revelation concerns Kyle's son, Caleb, who was killed years earlier. Kyle's ex-wife Jill confesses that Caleb was murdered by Sean Sanderson, a missing man known for preying on children in the park. Jill had hired Shane Maguire to kill Sanderson in retaliation, linking Shane to past crimes beyond the drug operation.

After these revelations, Kyle, burdened by the complex web of corruption, loss, and violence within the park, decides to resign from the National Park Service. He packs up and leaves Yosemite, symbolically passing his badge and horse to Naya, signaling a quiet but meaningful passing of the torch. Naya's survival and decisive action in the shootout suggest she will carry forward the responsibility of protecting the park.

The series closes with Kyle driving away from Yosemite, finally putting the ghosts of his past to rest but uncertain about his future, while Naya stands ready to face the challenges ahead.
