Amen (2011): Cast & Plot

Set against the brutal backdrop of World War II, this harrowing drama follows an unlikely whistleblower as he confronts the depths of Nazi cruelty and the slow, often reluctant response of the world to genocide. A Waffen-SS officer working with the SS Hygiene Institute, Kurt Gerstein becomes the bearer of a grim paradox: he helps design a method to purify water and eradicate disease, then discovers that the same hydrogen cyanide-based poison, known as Zyklon B, is being weaponized to kill Jews and other perceived undesirables in extermination camps. As the reality of his own creation sinks in, he is driven by a dire sense of responsibility to warn others, starting with the highest moral authority he can reach—the Vatican.
