Un alpino della settima 55 years old

A man promised to his dying mother to find and give a proper resting place to the remains of the father, a soldier, dead during WW1 and never found. It's an impossible and desperate quest since he died during Mount Piana battle that lasted two years and resulted in the killing of 14000 soldiers. But the obstinate man never gave up searching on the Dolomiti Mountains for all his life.
