Günter Zint and companions answer questions from director Axel Engstfeld about the life and work of Hamburg's exceptional photographer.

The footage, along with additional recordings, was edited into a 106-minute film from about 100 hours of material.

With her slap of the Federal Chancellor Kurt Georg Kiesinger in 1968, Beate Klarsfeld abruptly got known worldwide. The film highlights the significance of this act and its background.

In 1960 she went to Paris and met her future husband Serge Klarsfeld, whose father was deported to Auschwitz and murdered there.
