A 19th century Jewish family in the East End of London rise over three generations from abject poverty to become one of the world's wealthiest and most powerful pantheons in the fields of mining, politics, finance, motor sport and aviation.

Barnato tells the story of the meteoric rise of brothers Barney and Harry Barnato, from deprivation in 1850s London to become the founders and multi-millionaire owners of the world's largest diamond company, DeBeer's. Barney's life cut short under mysterious circumstances, his son Woolf inherits the fortune and uses it to bankroll the most iconic team in the history of motor-sport as the leader of the all-conquering 'Bentley Boys'. War hero, pilot, playboy, industrialist and super-sportsman with one last trick up his sleeve; Woolf passes the mantle to his daughter Diana. Glamorous high-society heiress, thrill-seeker and maverick WWII pilot, Diana's life, whilst tinged with sadness and personal tragedy, culminates in fulfilling a promise to her dying father by breaking the sound barrier in an Electric Lightning jet, becoming the fastest woman on earth. The true story of three generations of the incredible Barnato family.—Danny Rogers
