The Austrian architect Karl Schwanzer (1918-1975) was already considered a legend in his field during his lifetime - and is now world-famous above all for the BMW headquarters he designed in Munich. Max Gruber's semi-documentary portrait film shows Schwanzer as a pioneer and visionary who understood architecture as "materialized poetry" and as an instrument to make people happy. Nicholas Ofczarek slips into the role of Schwanzer and plays the architect as a dazzling personality, passionate artistic soul and eternal seeker, who sometimes worked to the point of self-abandonment to solve problems.
