As he withdrew from the public eye in his later years, Britten re-dedicated himself to composition with an intensity that defied his failing health. Featuring contributions from a host of friends and collaborators, John Bridcut's documentary examines the autobiographical impulses behind masterpieces including Death in Venice and the Third String Quartet, tells the inside story of Britten's battle with heart disease and reveals his "late period" as one of the twentieth century's bravest artistic achievements.
