Nocturnal Forum

The leading character, Number Six, is apparently a former secret agent of the British government during the Cold War. He is never identified by name and the exact nature of his job is never explicitly indicated, though numerous episodes provide clues. After resigning his position, he is kidnapped and held prisoner in a small, isolated, eccentric seaside resort town known only as the Village. The authorities there (whose identity and allegiance are never made clear) attempt to determine — "by hook or by crook" — why Number 6 resigned. Throughout the series Number 6 tries to escape while defying all attempts to break his will. He also sets out to discover the identity of the mysterious "Number 1", who presumably runs the Village. Towards the end of its run, the show deviated quite considerably from this template.

Although sold as a spy thriller in the mould of McGoohan's previous series, Danger Man, the show's combination of 1960s countercultural themes and its surreal setting had a far-reaching effect upon science fiction-fantasy-genre television and also popular culture in general.
