The epilogue to the film "The Laughing Man" (1966), which alternates between objectivity and anger, exposes the involvement of the West German mercenary Siegfried Müller in the war against the Congolese government Lumumba. In the sequel, new witnesses against Major Müller have their say, including a former school friend and a French paratrooper colonel. GDR lawyer Kaul reports on the status of the criminal proceedings against Müller, while the final images show the war criminal feeding the ducks in South Africa.
