S1·E4 The Saving Remnant

Erik Dorf complains to the other SS leaders that the executions of the Jews are not being efficiently done. An order is placed by Erik for Zyklon B (a lethal gas) for use at Auschwitz and other camps. Inga asks Müller to denounce her and have her sent to Karl at Theresienstadt. Felscher sells four of the secret drawings done by him, Frey and Karl, which depict the brutal conditions at Theresienstadt, to a Czech gendarme, which the SS get a hold of. Felscher, Frey and Karl are called in for questioning and then tortured. Karl survives and is sent to Auschwitz.
