After an unexpected checkpoint elimination, the group struggles when they must cross a precarious deep ravine by crawling over a bridge made of two parallel ropes to stay on their route. During the obstacle, one of the trekkers' injuries is revealed to be much worse than they've expressed, and other members start to question if they can truly make the journey to the summit. When the Mountain's Keeper offers a difficult but altruistic option, the group must decide if a few of them should carry heavy food bags so the entire group can benefit at checkpoint camp.
