Treadstone is a program of operative inside the CIA.
The program was first conceived of in the second half of the 1960s by a group of agent handlers who wanted to create a team of ultra-high trained agents - in truth, assassins - to be able to handle near-impossible missions and still find a way to make it out alive. It was given the green light and went into operation in the early 70s.
In order to produce such incredible weapons, it was decided that its would-be agents, recruits every one, would have to first be stripped of everything they were before, their memories completely erased so they had no ties to anything other than Treadstone and the missions they would be assigned. Since assassination was the likely goal of most of the missions, it was decided these trainees had to have their moral code completely removed so that the operatives would have absolutely no hesitation to kill without remorse.
There have already been two seperate series of chronicled adventures entered into this compendium. The first one, which established the existence of the program and its best (IMHO) graduate of that intense training, is . Another agent who would have his story told of his attempted 'normal' life after leaving the program is . The set of events told of in this entry have no direct connection to either of those agents other than the Treadstone program itself.
A twist in the strategy taken by the Treadstone personnel that is revealed in these episodes, differing considerably from those of Bourne and Hayes, is that these Treadstone agents were apparently fully trained and conditioned and then turned into sleeper agents to lie in wait, living 'real' lives in whatever potential hotspot the powers-that-be decided, ready to be awakened to carry out a specific action or series of actions once a trigger phrase is delivered. At that point, the minds of the operatives were trained to completely forget these lives and fall back on their original programming.
These tales take place in two time frames. One is in 1973 when a Treadstone operative, John Randolph Bentley, awakes and must escape from captivity by the Soviets. The other is in the present when a group of 'sleepers' are being awakened but the reason is unknown.
