During the Second World War, the son of a Grenoble collaborator went up to his grandmother's house on the Vercors plateau to wait for the war to end without him. On July 21, 1944, German troops overran the plateau. Forced to flee, he joins a small group of Resistance fighters and civilians, and struggles to survive for three days and nights.
