Tom and Noémie have fallen down a crevasse, and everyone bands together to get them out. Patty is reminded of her last moments with Ève, Karen’s sister, whose idea it was to organize this excursion.

Karen has been bearing a heavy secret ever since the climb began, and is finally starting to feel the weight of it. In a moment of soul-searching, Karen finds herself alone, face to face with a bear.

Morgan is very tense: her secret motivations for participating in this climb are getting harder and harder to keep hidden from her friends.

Determined to keep the promise they made to Ève, the women decide to flout the guides’ advice and continue the climb.
