A lumberjack by trade, Lorenzo has spent his entire life abroad, first in France and then in Switzerland. His body bent in two from years of hard work, Lorenzo carries his seventy-three years with ease atop forty-meter-tall fir trees. His work, in the endless expanse of beech and fir forests of Risoux, is both scientific and passionate. He lives alone, as his wife is in a clinic in Lausanne and a son was injured in the woods. Yet he hasn't lost his smile, he loves nature, and he approaches his relationships with other emigrants with irony and generosity. With them in the forest, Lorenzo prepares the charcoal kiln to transform beech branches into charcoal using the ancient ritual that unfolds over days and nights.
