A doctor from a Nazi death camp who fled to Spain continues his horrific activities, only to find himself in an iron lung.

Klaus (Günter Meisner) is an ex-Nazi doctor whose war-time post in a concentration camp enabled him to commit the most appalling sex crimes against boys. After the war, living incognito in Spain, he again gives in to his depraved desires, until shame and despair drive him to an unsuccessful suicide attempt. Soon after, Angelo (David Sust) enters his life, a strange, handsome young man. A perverse relationship develops between Angelo and Klaus, becoming ever more macabre as Angelo reveals he has found diaries detailing his employer’s war-time activities. Words turn to deeds, and a new spate of child killings begin…

Inspired by the true story of 15th century French knight Gilles de Rais, this psychological thriller is considered Spanish filmmaker Agusti Villaronga’s Masterpiece.
