the story, Number Six awakens in his flat in a furious mood, storming to his office to angrily resign. Only at the office does he realise that his appearance is not his own and that a year of his life is missing. Fearing that this is a ploy to force him to reveal confidential information, Six leaves the office, determined to find "Saltzman" (who became Seltzman in the broadcast version), the inventor of the body-swap machine. Meanwhile, Number Six's former employer, the Colonel, is shown to be in collusion with a mysterious, unseen figure, an apparent agent of the Village.

Number Two consents, and Six, Oscar and Saltzman are linked to the mind-transfer machine after Saltzman reconfigures it. The unconscious body of Number Six awakens with the correct mind in place. However, the process has been too much for the elderly Saltzman, who is dying. Oscar is
