Follow the hunt and ultimate capture of serial killer Keith Hunter Jesperson. An aspiring cop turned long-haul truck driver after a failed marriage, Jesperson strangled his first victim following an argument and was back on the road again the very next day, killing at least eight women over a five-year span as he crisscrossed the country. Upset after a woman falsely confesses that she and her boyfriend are responsible for one of his murders, Jesperson begins to taunt the authorities by sending a series of disturbing letters to newspaper editors, even scribbling confessions on the walls of highway rest stops admitting that he loved killing his victims. By signing his morbid notes with a happy face, he earned himself the notorious nickname, "Happy Face Killer" and forever left his mark of fear.
