The group gets caught in a terrible storm and emotions run high as some start to give up all hope of finding the bivouac... Luckily, Mark knows what he's doing.

Having been caught out in the storm and in desperate need of shelter, the two hikers from earlier suddenly burst into the bivouac. They prove themselves to be as disrespectful as ever, and Wolf decides he isn't going to stand for it...

The next morning, it's clear that Wolf has run away. Martin is adamant about following the rules and intends to break off the expedition. Lisa tries to convince him not to do that so close to the finish.

When the group learns who is responsible for Wolf's escape and, therefore, for the fact that the expedition has to be called off, everything gets out of control.

Will Mark and his companions continue their ascent? They get an unpleasant surprise that could jeopardize everything...

The situation seems hopeless. How are they all supposed to cross the crevasse? Then, completely out of the blue, Harpo makes a run for it... The final stretch to the summit is dramatic and extremely moving!
