France, 1942: A serial killer stalks the streets of Occupied Paris. Using the chaos of the war to his own advantage, psychotic doctor Marcel Petiot poses as a resistance operative and preys on those most desperate to flee the Nazi regime - Jews, criminals and underground partisans. As the body count rises, both the French police and the Gestapo race against time to bring him to justice.

"In the shadows of occupied Paris, he preyed on those seeking escape—until the city itself became his deadly network."
