Sara, Patty, Noémie, Valérie, Karen, and Morgan arrive at the train station. The six women feel enthusiastic as they head off to place their friend’s ashes at the top of the Dôme de la Lauze mountain.

Noémie is extremely anxious as she awaits her test results to find out whether or not her cancer has returned. To make matters worse, she’s completely broke.

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.

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.
