Every Rembrandt exhibition is eagerly anticipated, but a once-in-a-lifetime show at London's National Gallery and Amsterdam's Rijksmuseum that took 15 years to prepare was remarkable. With exclusive and privileged access to both galleries, this film documents this landmark exhibition while interweaving Rembrandt's life story with behind-the-scenes preparations at these world-famous institutions. Rembrandt is the greatest artist that ever lived to many, and this film seeks to explore the truth.
