In 1995, FBI profiler Jim "Fitz" Fitzgerald joins the Unabom Task Force. Fitz recommends new methods of profiling but finds no allies among the agents in charge. In 1997, Fitz is tasked with confronting Ted Kaczynski, the Unabomber.
Linguist Natalie Rogers helps Fitz find clues about the Unabomber's identity in the Manifesto, but their findings face skepticism at the UTF. In 1997, Ted claims he can invalidate all of the evidence against him.
