One Chance is the remarkable true story of Paul Potts, cell phone salesman by day, amateur singer by night, who stepped onto the stage in the premiere season of Britain’s Got Talent, and changed his life. When he opened his mouth to sing Puccini’s “Nessun Dorma,” judge Simon Cowell and millions of viewers were stunned. Paul went on to win the show’s competition and become a YouTube sensation and multiplatinum artist virtually overnight. Filled with personal recollections not featured in the film, this is the wonderful story of the shy, bullied Welsh store manager who seized his biggest dreams and won audiences around the world.
