Borchert and Dominique Kuster take over the defense of the taxi driver Jrg Zollinger. Captain Furrer suspects him of the murder of a passenger, the African investigative journalist Nuka Baluba. All the evidence incriminates the uncontrolled suspect, whose testimony initially seems unreliable. Borchert is suspicious of the fact that public prosecutor Dietrich is quick to commit to Zollinger. The "lawyer without a license" suspects that Baluba's research into child labor in cobalt mines in the Congo has something to do with the murder.
