During an expedition to Tibet in 1999, Conrad Anker and Kris Erickson lost their companions Alex Lowe and David Bridges to an avalanche. The enormous snowslide on the southern face narrowly missed Conrad Anker, who however survived miraculously. To honour their memory and celebrate their accomplishments , Conrad and Kris decide to be the first to face the Nutcracker, an ice climb route in the Hyalite Canyon in Montana. It is a difficult opening but above all an opportunity to recount and recall a life made up of ascents and sacrifices, of joy but also pain.
