The Real Cracker follows the profilers as they advise on five violent crimes, including what is reputedly Britain's most unsolved crime - over a period of ten years, a series of women have been raped at a beauty spot, yet no forensic evidence has ever been discovered. Boon investigates the strange case of 30 women over 80 being raped by a 30-year-old man and the murder of an 87-year-old woman in Sussex. Badock inspects the evidence of the horrific murder of a 23-year-old woman in Kent - police turned to him in order to dismiss her boyfriend from the investigation. As the detective work continues, the psychiatrists advise the police who to look for, who not to look for and how to search for them. Once suspects are arrested they even devise detectives' interview strategies and listen in as suspects are questioned, advising who is guilty and who is not.
