Kiefer is Germany's most controversial and reclusive artist. He is also its most successful. The millions his work commands in the auction houses and his popularity with collectors belies the sombreness of the subject matter - Germany's past.
Through Wagnerian legend, historical conjecture and ancient mythology, Kiefer offers a personal view of Germany today that is both an exorcism and a warning.
Never before filmed, Kiefer has collaborated with Arena in an unusual portrait in which he sets out to 'disinter some corpses from Germany's past'.
