He’s a key figure in the clandestine wranglings of two superpowers: the United States and China. The FBI announced a five-million-dollar bounty for information leading to his arrest. Intelligence agencies and investigators have been trying for decades to stop him in his tracks: the arms dealer Karl Lee. The documentary follows Karl Lee’s trail across four continents, from Washington and New York to Tel Aviv, from Europe to Teheran, Beijing and Karl Lee’s factory in northeastern China. The prize-winning investigative journalists Philipp Grüll, Frederik Obermaier and Bastian Obermayer provide unique insights into the world of spy agencies and diplomacy. At the same time, the film is a lesson in the powerlessness of the West and the rise of China - as well as an unflinching appraisal of the new world order.
