SYNOPSIS

A true crime documentary series that reveals new and previously unknown aspects of the alleged serial killer, ultimately raising the question: Was Jack Unterweger possibly innocent?

The story revolves around the unique manhunt for Jack Unterweger, an Austrian convicted murderer and alleged serial killer who was suspected of multiple prostitute murders in both Europe and the United States. Unterweger gained significant international attention because, after serving a 15-year prison sentence for the murder of 18-year-old Margret Schäfer in 1974, he was released on parole in May 1990 and achieved fame and recognition as a writer and a successful case of rehabilitation before falling under suspicion for the serial killings of prostitutes. His crimes and his apparent ability to lead a double life and manipulate others made him one of the most fascinating and disturbing personalities in criminal history.
