After the tragic death of her sister, Jax seeks an escape in extreme sports. Together with her friend Luce, she takes on a deadly challenge: climbing the legendary face of Mount Kwan in Thailand. What was meant to be an adrenaline rush soon turns into a desperate fight for survival. A sudden rockfall cuts off their escape route, leaving them trapped on a precarious ledge 3,500 meters above the ground. Suspended between the sky and the abyss, exposed to grueling heat, and cut off from water and the outside world, Jax and Luce must confront their fears, push past their limits, and fight for their lives.
