The Investigation is a dramatic reconstruction of the Frankfurt War Crimes trials, based on the actual evidence given. This testimony, concerning Auschwitz and the atrocities which were enacted there, has been edited and extracted by Peter Weiss into a dramatic document that relies solely and completely on the facts for its effectiveness.There is no artistic license, no manipulation of facts and figures, no rearrangement of events for theatrical effect. Nameless witnesses stand and recall their appalling memories of Auschwitz, allowing us to bear witness to their painful and painstaking search for truth and ultimately justice. What emerges is a chastening and purging documentary of deeply moving power.
