Enrico Dini is on a quest to revolutionize the way we view construction – by developing a vast machine that can 3D-print huge structures made from real sandstone. But with his family life in tatters, and his business on its knees – has he sacrificed too much for the greater good? The film is a poignant, funny and awe-inspiring documentary that delves into the troubled mind of a genius intent on changing the world forever.
