(Click CC for Subtitles) Deep in the forests of Northern Italy resides the prized white Alba truffle. Desired by the wealthiest patrons in the world, it remains a pungent but rarified mystery. It cannot be cultivated or found: the only souls on Earth who know how to dig it up are a tiny circle of canines and their silver-haired human companions-Italian elders with walking sticks and devilish senses of humor-who only scour for the truffle at night so as not to leave any clues for others. Still, this small enclave of hunters induces a feverish buying market that spans the globe.
With unprecedented access to the elusive truffle hunters, filmmakers Michael Dweck and Gregory Kershaw follow this maddening cycle from the forest floor to the pristine restaurant plate. With a wily and absurdist flare, The Truffle Hunters captures a precarious ritual constantly threatened by greed and outside influences but still somehow protected by those clever, tight-lipped few who know how to unearth the magic within nature.
