Zack wakes trapped in a car during a sudden mudslide and realizes he's been reborn to the day he was buried alive. He remembers waiting seven days in his prior life, losing oxygen and becoming fully paralyzed after Zed and Ruby left him. Now Zed says he'll care for Flora, Luna and Ruby but demands Zack's creations and flashes compromising photos to silence threats. Ruby tells Zack, "I love Zed more," abandoning him. Betrayed and haunted by his death, Zack decides to expose Zed and vows revenge, leaving his plan unresolved.
Zack lies trapped under a mudslide while Flora, Luna and Zed stand above him. They argue over rescue after the flash flood: the car got stuck, Zack drove off without waiting, and the others admit they drugged him before he fell. The road is blocked and repeated call attempts fail, so outside help seems impossible. Accusations and guilt rise as they debate abandoning him or risking a rescue. Deep in the mud, Zack refuses to stay passive: "I have to get out. I want to live." The episode closes on his unresolved attempt to escape.
A driver trapped in a car after a mudslide refuses to smash the sunroof for fear mud and rocks will pour in. Zack is missing and his fiancée begs Flora and Luna to save him, saying she would still marry him if he survives. The rescue team says the area is too large, the flood is ongoing and searches can’t start, so Flora and Luna volunteer to go while Zed is ordered to focus on a competition. The trapped person conserves phone battery and one bottle of water, screams for passing villagers, and a man nearby hears the cries—rescue remains uncertain.
After a flash flood someone cries out, "I'm trapped in the mud," struggling in a hollowed space with no signal and almost no water. At the company, colleagues learn Zack missed his first Path to the Throne round; his last phone pinged on the mountain road hit by the flood, so they suspect he's missing because of the disaster. The trapped person decides to act: they discover a hollow cavity and conclude that opening the window could let them climb out. The episode ends with them determined to pry the window, fate unresolved.
After a flash flood buries Zack's car in a mudslide, Whitney Lynd, CEO and Zack's agent, rushes to the Shelley house seeking him. Rescue teams say the road is wiped out and further landslides make entry impossible; every hour Zack stays buried is another step toward death. Zack's fiancée breaks down, blaming herself. Nearby, a survivor finds only bitter, muddy water and resolves to filter it to avoid illness. Zed and Ruby made it back to the Shelley family and may know Zack's location, so Whitney gets in the car and heads there as time runs out.
After a deadly mudslide leaves Zack missing and rescue teams blocked, Zed vows to find him personally. Family members argue: some tell Zed to wait and focus on safety, while others accuse a survivor of having fled and the survivor angrily denies desertion. Tensions escalate as relatives insist that Zed continue in the upcoming Path to the Throne competition to honor Zack’s dream. Torn between searching and pressure to compete, Zed chooses to enter the contest — and advances to the Round of 32 — while Zack’s fate remains unresolved.
Buried in his car after a mudslide, Zack struggles two days without signal and dwindling oxygen. He plans to push a hollow tube through the soil to bring in air or alert passersby, but fears the pipe will clog. On the surface, people at the site confront rescue personnel: the disaster is massive, teams are short-handed, the route is blocked and a second collapse is possible. After three days and grim odds, the rescue leader declares the operation too dangerous and calls off the rescue, leaving Zack’s survival unresolved as air runs out.
A rescue team refuses to disclose where Zack is buried until it's safe to enter. Told that friendship shouldn't override safety, a determined person rejects orders and vows to save Zack themselves. Denied location details, they start assembling hollow tubes as an improvised breathing shaft and push them into the mud, but the pipe keeps blocking and a silt layer halts progress. Exhausted and still beneath the surface with air and time running out, the rescuer remains trapped and whispers, "Am I really going to die here?"
At the site, a person refuses to accept a repeat of a past death, shouting, "I refuse to relive the way you killed me last time!" Meanwhile a rescue crew scrambles to find missing Zack; there is no signal, so the tech team activates a program that detects Zack's phone within 100 meters. The leader assembles Zed and Ruby and moves into the site. The search escalates into frantic breaking and shouting as crews try to force access. The key turn: Zed forces a breakthrough and Zed advances, but Zack's phone alert hasn't been confirmed—rescue results remain unresolved.
