Well, it is and it isn't. Tricky to explain without giving too much away. Basically MKULTRA experimentation was given as an excuse by the CIA for the death of a scientist that was working on biological weapons type stuff for the CIA. The actual cause/reason for his murder? That's the topic pretty much. That and the scientists son's obsession with the murder spanning half a century and involves the son going through great lengths to get the truth about what actually happened to his dad.
