Veteran Chamonix mountain guide Michel Servoz and the young aspiring guide Patrick Falavier attempt to climb the west face of the Dru in the Mont-Blanc massif. When they are gone for five days, the captain of the gendarmerie in Morteau is worried, but he cannot undertake research for a rescue without the permission of the family.
