Failed the living for the dead

Hungarian Saul Ausländer and his pals are deployed as workers ("Sonderkommandos") ushering fellow jews into gas chambers, collecting their valuables for the nazis, burning the bodies and tossing the ashes into a river. Never told, but apparently it all is taking place at Auschwitz, but anyways it's extremely well executed the whole final holocaust -thing, in all its mindless brutality and complexity of evil.
