- The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top-secret messages.

Stalker (Russian: Сталкер, IPA: [ˈstaɫkʲɪr]) is a 1979 Soviet science fiction film directed by Andrei Tarkovsky with a screenplay written by Arkady and Boris Strugatsky, loosely based on their 1972 novel Roadside Picnic. The film tells the story of an expedition led by a figure known as the “Stalker” (Alexander Kaidanovsky), who guides his two clients—a melancholic writer (Anatoly Solonitsyn) and a professor (Nikolai Grinko)—through a hazardous wasteland to a mysterious restricted site known simply as the “Zone”, where there supposedly exists a room which grants a person’s innermost desires. The film combines elements of science fiction and fantasy with dramatic philosophical, and psychological themes.
