After unemployed ITC expert Jochen Kappler calls Hanna Lohr's nocturnal radio talk-show to announce his suicide, his corpse is found at home, but it's staged: murder by poison. Jochen Kappler's financially struggling step-father Heinz Mahlmann, who calls him a parasitic loser, rowed with him the night before over cash. Study friend Hugo Stange was trough with his sponging. Radio presenter Hanna Lohr and devoted studio technician Nils Boden recently paid Jochen Kappler his share for the radio format, which they originally developed as college project, yet were blackmailed.
