The documentary Holocaust: Concentration Camps - Dachau and Sachse documents the events that transpired at two of the most infamous Nazi concentration camps. Explicit archival footage is used to capture the daily realities of two of the Third Reich's most notorious concentration camps -- Dachau and Sachsenhausen -- where thousands of innocent prisoners died. At Dachau alone -- the more notorious of the two camps -- more than 500 experimental operations were performed on healthy subjects during 1941 and 1942.
