Mino arrives at the summit station in the middle of the first artillery barrage of the Austrian summer offensive of 1916. Mino hurries to call his father on the observations posts telephone and learns that his mother is alive and in Treviso. The phone cable and the aerial tramway are destroyed by the intense shelling and Mino runs away to meet his father down in the valley. But he soon must hide in a crevice from the bombardment. When he comes out the Austrians have swept away the Italian positions and Mino finds only one gravely injured Italian survivor at the observation post. Mino alone carries and drags the wounded Lieutenant from the mountain plateau of Asiago to the valley below. After some days an Italian patrol finds them and brings them to a hospital.
