'Many Happy Returns' was the fifth episode of 'The Prisoner', originally broadcast on the eleventh of November, 1967.
Number Six wakes up one morning to find himself alone. The utilities in The Village are all switched off and the place is utterly deserted. After making sure that it's not all just another trick, he takes lots of photographs and, in typically ingenious fashion, builds a raft and sets sail for freedom.
I'm not going to say anymore, just in case you might want to watch it. It's a classic piece of television drama - wordless for almost half its running time, utterly logical, and with a brilliant and wrenching twist. Genius.
