In World War II, Kurt Gerstein, a sanitation engineer and family man, is tasked by the SS to purify water for the German Army. He's later invited to help eradicate plagues in concentration camps, where he develops lethal gas Zyklon-B. Horrified by the SS's true intentions, Gerstein decides to expose the genocide to the Pope and the world to save Jewish families.

Amen.
In a daring mission, a fearless SS officer and a devoted Jesuit priest join forces to reveal the brutal truth about the Nazi regime's treatment of Jews, risking everything to bring their findings to the Pope's attention.
