Die Sonneninsel

Frankfurt's city architect and planner Ernst May and architect Martin Elsaesser became pioneers of Neues Bauen (New Building) in the 1920s. May fled from the Nazis to the Soviet Union, Elsaesser to a secluded island in eastern Berlin. The grandson of Elsaesser tells the story of his famous grandfather's forced dropout existence and a tragic ménage à trois with the help of previously unknown private footage.
