Plot Overview

The story centers on Frank (Richard Roxburgh), an experienced and pragmatic cave diver, who leads an elite team on an expedition into the world’s largest and most remote cave system in Papua New Guinea. The group includes Frank’s estranged son, Josh (Rhys Wakefield), and a team of skilled divers and explorers. Initially, the journey is fueled by the thrill of discovery, but everything changes when a sudden storm causes a flash flood, sealing their exit and leaving them trapped deep underground.

As the water levels rise, the group faces dwindling oxygen, depleting supplies, and a maze of treacherous, submerged tunnels. To survive, they must forge a new path to safety through the labyrinthine cave system, contending with relentless physical and psychological challenges. As the pressure mounts, personal conflicts erupt, fear intensifies, and the reality of survival forces each character to confront their limits—and their humanity.
