|I am not a number --- I am a free man.|

Number Six is monitored heavily by Number Two, the Village administrator acting as an agent for an unseen "Number One". A variety of techniques are used by Number Two to try to extract information from Number Six, including hallucinogenic drug experiences, identity theft, mind control, dream manipulation, and various forms of social indoctrination. All of these are employed not only to find out about why Six resigned as an agent but to extract other dangerous information he gained as a spy. The position of Number Two is filled in on a rotating basis; in some cases, part of a larger plan to confuse Number Six, while other times as a result of failure for interrogating Six. A major theme of the show is individualism versus collectivism.
