MANIFESTO – Ted Kaczynski, also known as the “Unabomber,” terrified the nation over the span of 20 years from the 1980s through the early 1990s. A new scripted series from Kevin Spacey and Dana Brunetti’s Trigger Street with the pilot script from writer Andrew Sodroski, MANIFESTO will tell the story of how the FBI brought down one of the most infamous criminal masterminds in the world from the point of view of an FBI profiler. The series will trace how FBI Agent Jim “Fitz” Fitzgerald challenged the “old school” ways with his radical new approach to intelligence gathering. Prior to Fitzgerald’s involvement, the profile of the perpetrator took a completely different direction. Fitzgerald had training as a profiler, but it was his focus on linguistics that became vital to breaking the case. He believed that the key to unlocking the true identity of the Unabomber would be found in the language of The Manifesto, a detailed account of some of Kaczynski’s plots.
