Set in Berlin on the eve of war, police lieutenant Wilhelm Krützfeld over the course of 24 hours navigates a city turned into a powder keg. Following the assassination of a German attaché in Paris, which is wrongfully labelled a “Jewish terrorist attack” by Nazi propaganda, the people turn on the perceived “enemy within” and violently descend on Jewish neighbourhoods and places of worship. As the city spirals into chaos and dozens of innocent people are murdered, orders are handed down to “let the people riot.” Krützfeld is faced with the moral choice between upholding the system or taking a stand.
