Please answer the following question: Build a movie plot around this: Who is Armstong's official guard? Hermann Gromek
Answer:
Michael Armstrong (Paul Newman), an American physicist and rocket scientist, is traveling to a conference in Copenhagen with his assistant and fiancee, Sarah Sherman (Julie Andrews). Armstrong receives a radiogram to pick up a book in Copenhagen; it contains a message which says, "Contact in case [of emergency.]" He tells Sherman he is going to Stockholm, but she discovers he is flying to East Berlin and follows him. When they land, he is welcomed by representatives of the East German government. Sherman realizes that Armstrong has defected, and is appalled that, given the circumstances of the Cold War, if she stays with him, she will likely never see her home or family again.Armstrong visits a contact, a "farmer" (Mort Mills), where it is revealed that his defection is in fact a ruse to gain the confidence of the East German scientific establishment, in order to learn how much their chief scientist Gustav Lindt (Ludwig Donath) and by extension, the Soviet Union, knows about anti-missile systems.Armstrong has made preparations to return to the West via an escape network, known as . However, he was followed to the farm by his official guard, Hermann Gromek (Wolfgang Kieling), an East German security officer. Gromek realizes what is and that Armstrong is a double agent, and as Gromek is calling the police, a tortuous fight scene commences that ends with Gromek being killed by Armstrong and the farmer's wife (Carolyn Conwell). Gromek and his motorcycle are then buried. The taxicab driver (Peter Lorre Jr., uncredited) who drove Armstrong to the farm, however, reports on Armstrong's behavior to the police.Visiting the physics faculty of Karl Marx University in Leipzig, Armstrong's interview with the scientists ends abruptly when he is questioned by security officials about the missing Gromek. The faculty try to interrogate Sherman about her knowledge of the American "Gamma Five" anti-missile program, but she refuses to cooperate and runs from the room, even though she has agreed to defect to East...
