He was a brilliant mathematician who turned his back on his training and society. Alone in the Montana wilderness he conducted an 18 year campaign of terror that stymied law enforcement agencies nationwide.  For years very few people knew the name Theodore Kaczynski. But the "Unabomber" was one of the nation's most wanted criminals killing and wounding scientists engineers and high-tech professionals with carefully-crafted homemade letter bombs. Here FBI agents including Oliver "Buck" Revell who headed the Unabom investigation trace the often-frustrating course of their long inquiry from the first bomb in 1978 to the arrest of Kaczynski at his remote Montana cabin. The program also traces Kaczynski's life before he dropped out of society interviewing his college roommate and a childhood neighbor.  From suburbia to the life of a hermit from promising career to the most-wanted list this is a fascinating look at the fractured life of one of the 20th century's most enigmatic and famous criminals.
