The plot centres around an ex British secret service agent who, when he mysteriously resigns, is abducted and brought to an Alice in Wonderland like village full of other captive spies to have his secrets extracted. The methods of extraction are not so much brutal as they are cerebral (even strangely whimsical at times) and the village is a prison without bars, full of bright colours and banal leisure activities. Aside from Number Two (no one in the village is allowed a name and are instead assigned numbers), it's often difficult to ascertain who is doing the keeping and who is being kept.
Patrick McGoohan has left a brilliant accomplishment in his wake and I'll be watching (and relishing) more episodes of The Prisoner tonight.
“I will not be pushed, filed, stamped, indexed, briefed, debriefed, or numbered. My life is my own.”
