Love how the title sequence with that terrific Ron Grainer theme welling up behind it encapsulates in three minutes the who!e premise for what was to follow.
A top-level secret agent (possibly John Drake- a case of art imitating life imitating art?) angrily resigns his position but is then kidnapped and placed in an apparently sleepy but ultra-modern village in an unknown location where he is expected to acclimate himself to the mundane unchanging way of life and also to give up information as to why he resigned. This brings him into contact with the ever changing Number 2, the village controller tasked with breaking the new Number 6 as the new arrival is termed and what follows is a succession of episodes where the individual puts himself against the system, not only asserting his own free-will but resisting the constant intrusion into his own privacy.
This classic scene-setter introduces Patrick McGoohan as the blazered, scowling, fiercely resistant Number 6 determined to beat every new Number 2 and eventually escape the Village. He tries every conventional method in this first chapter to get away only to be thwarted every time especially when he learns of the existence of "Rover" an absorbent roaring sci-fi bubble which acts as a sort of guard dog for the premises.
McGoohan is magnificent in the lead role in one of those rare TV shows which comes along and is completely unlike anything which has gone before. It baffled much of the public when first broadcast but makes more sense in today's more enlightened times.
Give it a chance and it will imprison your interest for all 17 episodes.
