Moments later, plastic surgeon Dr. Petrov leads Stalin into the operating room and transforms his face so that he is unrecognizable. After his handlers announce publicly that Stalin has died, they secret him away to a hideout, where Greta Grisenko serves as his nurse. Meanwhile, Gretas twin sister Lili continues searching for her, as she has been ever since Russian troops invaded their home country of Lithuania and took Greta, against her will, to Moscow. Earlier, Lili had engaged private investigator Steve Anderson, an American living in Berlin, to find Greta, and now locates him there and asks why he has failed to contact her with information about her sister. Steve has discovered that Greta is working in Moscow and, despising Communists, refuses to work with Lili until she convinces him that her sister is an innocent victim of the Russians.Steve takes Lili to the home of Mischa Rimilkin, a onearmed espionage agent who reveals that Greta has been working for Petrov. Upon receiving assurance from the American Army that Lili is not a spy, the men divulge to her that Dasha, now confined to a mental hospital, claims that Stalin has been surgically altered and is living clandestinely with Greta. ........
