Description: The time is 1973. The Cold War of the mid-20th Century continues to damage international relations. Britain’s Secret Intelligence Service (SIS), a.k.a. MI6 and code-named the Circus, is striving to keep pace with other countries’ espionage efforts and to keep the U.K. secure. When things go awry, it's up to top lieutenant, George Smiley, a career spy with razor-sharp senses, to get things back on track. (Focus Features)
