The very loyal Peter Guillam getting into a lot of trouble for the sake of his best friend George Smiley. A powerful scene with masterful acting (the tension is incredible, even without sound on). In this scene (episode 4 "How It All Fits Together") : Michael Jayston, Bernard Hepton, Warren Clarke, Joe Praml, Ian Richardson, Michael Aldridge, Terence Rigby, Marjorie Hogan.
