Fall 2: Deadpoint

After the death of Shiloh Hunter, her grieving sister Jax meets Shiloh's friend Luce to sell Shiloh's recovered truck. Inside, Luce finds Shiloh's scrapbook of locations where she planned to climb and perform stunts for her social media followers. Luce eventually persuades Jax to accompany her to a plank walk on Mount Kwan in Thailand, where a dragon statue is said to "eat your fears." In Thailand, they visit a secluded bar and use a code phrase to meet Jon, a non-native guide who agrees to take them on the plank walk for a fee paid by Luce. Jon warns them that the mountain has been permanently closed because of earthquakes, rock slides, and heavy rain.

The following day, Jax, Luce and Jon climb the restricted mountain. Jax nearly falls from a ladder, but the trio continue using a "clip-in clip-out" method to cross the "Devil's Elbow". Heavy rain triggers a rock slide that separates Jax and Luce from Jon, who they believe has been killed. As they try to turn back, another rock slide destroys part of the planks and nearly pulls Jax from her clip. The women become stranded at the Devil's Elbow, unable to proceed or retreat, while their backpack hangs from an inaccessible support.

That night, they use Jon's laser pointer to signal the bar, but the bartender closes the blinds. The next day, Luce reveals that she has terminal cancer and has been avoiding her parents' calls. Meanwhile, Jax's grief, fear, exhaustion and altitude sickness begin distorting her perception. Reviewing Shiloh's old camera footage, she realises that the woman beside her is not the Luce from Shiloh's life. The woman admits that her real name is Billie. A fan of Shiloh's channel, Billie discovered that Jax was selling Shiloh's truck and pretended to be her sister's friend, knowing Jax would not sell it to a fan. As she grew closer to Jax, Billie developed a genuine emotional connection with her and sought to help her overcome her grief and fear through the climb.

The following day, Jax and Billie realize that they are growing weaker. Using their backpack radio, they discover that Jon survived the rock slide and was merely knocked unconscious. Billie attempts to retrieve the backpack but is badly injured and nearly falls to her death before Jax saves her. Jax reaches the railing and calls Jon for help. Jon finds them, rescues them from the Devil's Elbow and contacts the authorities, requesting a helicopter to meet them on the other side of the mountain. The trio reach the dragon statue, where Jax pays tribute to Shiloh.

They then cross the final section of the plank walk, an unstable bridge spanning a high gap between Mount Kwan's peaks. Exhausted, Billie opens one of the O2 tanks Jon supplied and discovers drugs inside. Jon reveals that he took them on the illegal climb because he is smuggling fentanyl across the border, using climbers as unwitting drug mules. He also reveals that the approaching helicopter belongs to other traffickers rather than the authorities. Furious, Billie throws an O2 tank from the mountain. Jon responds by pushing her to her death.

Jon then attempts to kill Jax, but falls to his own death. When the helicopter arrives, Jax uses the remaining drugs as a bargaining chip and is rescued and taken back to the bar, where she buys a drink in memory of Billie. She later opens Shiloh's scrapbook and discovers another destination: Hell's Chasm.

Elsewhere, Shiloh's friend Becky Connor receives an invitation to Hell's Chasm to celebrate Shiloh's life.
