Kurt Gerstein: Der Christ, das Gas und der Tod (2005)

Portrays the Protestant Kurt Gerstein, who - although a member of the Confessing Church - joined the Waffen-SS in 1941 with the declared aim of gaining a glimpse into the machinery of the Holocaust. The "Gerstein Report", written shortly before his death in 1945, is one of the earliest and most important eyewitness documents of the Holocaust.
