All become green

Young prosecutor finds out that Auschwitz wasn't an amusement park and Dr. Josef Mengele was one of the sickest motherfuckers ever faced the earth. It all comes news to him, it's the late 50s, the scars haven't been healed in Germany, albeit being a sensitive subject he intends to imprison all the former members of the nazi party still walking free. Based on the 1963 'Auschwitz Trial', so at least it was somewhat eye-opening the whole thing.
