苏联边防军
The film begins in 1989 when Sergeant Alexander (Sasha) Belov, (nicknamed Bely, or "white") has finished his national service in the Soviet Border Troops, and returns to his home in Moscow. He is greeted there by his three childhood friends, Kosmos Kholmogorov (or Kosmos (Kos)/Space), Viktor Pchyolkin (Pchyola/Bee), and Valery Filatov (Fil/Phil). His return, however, shows that perestroika has deeply transformed the Soviet Union life and both Kosmos and Pchyola have turned to criminal racket on Moscow's markets. They try to lure Sasha to join them, but Belov abruptly refuses and instead has ambitions to attain higher education in vulcanology.
