The documentary film tells the story of Zucchero Sugar Fornaciari through his words and those of colleagues and friends such as Bono, Sting, Brian May, Paul Young, Andrea Bocelli, Salmo, Francesco Guccini, Francesco De Gregori, Roberto Baggio, Jack Savoretti, Don Was, Randy Jackson and Corrado Rustici. A journey of the soul which, thanks to images coming from Zucchero's private archives and from the "World Wild Tour", his last and triumphant world tour, goes beyond the portrait of a successful musician reaching into the doubts and fragilities of 'man.
