Four Rational People: The Emerson String Quartet embarks on the final season of a fifty-year history that includes 9 GRAMMYs and thousands of concerts. Interweaving vivid memories with delicate observations of life on the road, the film explores the difficult decision to walk away from the things they cherish: the music they play and the friends they hold dear. At once a frank examination of the tyranny of aging and a cri de cœur to pass the torch to a new generation, the film culminates with one final performance, leaving all to ponder what happens to us after the final curtain.
