August 1945. A small town in post-war Germany. Here, in a gloomy castle, lives the out-of-mind Baron von Ledendorf, who imagines himself to be the devil. Four young officers secretly come to him, with whom the baron makes a deal: he promises them a long life and a successful career in exchange for their souls. In sixty years, the officers will have to give up everything they have, including their own lives and the lives of close relatives... And now sixty years have passed. Under strange circumstances, the famous artist Beloyarsky dies, then the eminent director Urbanovich, followed by the composer Basardin. These are the same officers who sold their souls. Former police officer Vadim Gorodetsky is immersed in the Mystery of mysterious crimes, who, after a severe head injury, suddenly acquires psychic abilities. We must find the fourth officer at all costs to save his life, if, of course, it’s not too late...
