Psychopaths are a ruthless breed who lie, manipulate and sometimes murder, with no hint of conscience of remorse. One per cent of the population are classified as psychopathic. There may be one in your office. There could be one on your street. They are all around us, often in positions of power.
Psychopath Night unravels the mystery of this minority, with the help of leading experts. The programme goes inside the minds of psychopaths, finds out how to spot a psychopath, and meets real psychopathic killers.
The programme also gets to know some familiar faces who are high on the psychopathic scale, including a star of the England football team.
There's also a countdown of the Top 10 movie psychopaths, as selected by experts, including a real-life Clarice Starling who uses Hollywood movies to teach her FBI trainees about psychopaths and how to handle them.
Psychopath Night reveals everything you ever wanted to know about psychopaths, and perhaps a few things you didn't.
