Drama series about the attempts to unmask Ludwig Kessler, the fictional head of the Gestapo in Belgium from the series SECRET ARMY, who escaped punishment, changed his name to Manfred Dorf, and became a successful businessman.
Kessler is outraged by the way his old Nazi comrades have treated him - they evidently look on him as disposable, and the old S.S. man is on his own. He sees that he has the knowledge to create havoc by changing sides.
