Paolo is a social worker in the scarcely populated and rugged Valle Cannobina, in the Verbano area in Piemonte, on the frontier with Switzerland. Every day he goes from house to house, providing home care to elderly people in difficulty, who have often remained alone in the valley and who could not survive without him. According to their needs, Paolo transforms himself into nurse, consultant, adviser, friend, grandson or odd job man. He brings home the shopping, gives advice and helps with domestic work or daily cleaning. A coffee, a few words exchanged with each person, with their sometimes rough style and character, and goodbye: he gets into the car and heads for a new house, another person, often waiting for him on the doorstep, and a new need to satisfy.
