Die letzte Instanz

An old lady shoots in front of the district court on the homeless Hellmer, who can escape unhurt. Ms. Altenburg comes from Görlitz and was visiting Berlin with her church group. After the crime, Ms. Altenburg suffered a fainting spell and is in hospital. Lawyer Joachim Vernau offers his help to the woman - he travels to Görlitz to get her personal belongings. When he returns, Margarete has died in the clinic. Vernau does not let go of this case: The old lady can not have planned the murder attempt on Hellmer alone. Who got her the weapon? And what is the motive?
