The thrilling game of survival reaches its most emotionally charged day yet, as the hikers come face to face with their loved ones on a video call before being ordered to abandon one of their own at camp and sneak out in the dead of night.

An obstacle in the ice challenges the final hikers' nerves and with it comes a brutal sacrifice. An agonising decision then falls to one hiker alone; the ascent to the summit was never going to be easy.
