Just out of jail and still searching for his late beloved Beniamina, crumpled English archaeologist Arthur (Josh O'Connor) reconnects with his wayward crew of tombaroli accomplices – a happy-go-lucky collective of itinerant grave-robbers who survive by looting Etruscan tombs and fencing the ancient treasures they dig up. Arthur isn’t interested in the artefacts, though; he’s seeking a legendary door to the underworld, and to Beniamina.
