In this episode, broadcast on 6 June 1995, the early history of the Central Intelligence Agency's (CIA) use of brainwashing and mind control is examined. Its thesis is that a search for control over the past, via medical intervention, had to be abandoned, and that in modern times, control over the past is more effectively exercised by the manipulation of history. It concludes that despite successful attempts to remove memories of the past, doing so often left an emotional void that was hard to refill.
