Peter Nagel is Schleswig-Holstein's most famous painter and a founding member of the artist group "Zebra," which launched New Realism in Germany in the 1960s. His "greatest" work is a ceiling painting that has adorned the ceiling of a school in Kiel since the mid-1970s. Director Christian Mertens, himself a former pupil there, returns to his old school 25 years later and immerses himself in the world of Peter Nagel: How do you do something like that? Who does something like that? And what kind of person is he?
