The fall
Leamas pretends to fall apart. He drinks, is fired and takes a job in a library, where he meets Liz Gold, a young Communist. They fall in love. Then he assaults a grocer and goes to prison, to look like a disgraced man ready to defect.
Defection
Leamas is approached by East German agents and taken to East Germany. He gives information suggesting that Mundt is a British double agent. Fiedler, Mundt's Jewish deputy, believes it and arrests Mundt.
The tribunal
At a secret trial, Mundt's defense brings in Liz Gold, who has been invited to East Germany. Her testimony reveals that the British secretly paid her bills, which shows that Leamas's defection was a setup. Mundt is cleared.
The truth
Leamas realizes that Mundt really is a British agent, and the whole plan was to destroy Fiedler, who was getting close to the truth. Mundt helps Leamas and Liz escape. At the Berlin Wall, Liz is shot. Leamas, disgusted, climbs back down and is shot dead beside her.
