In 1990, John Willis of Chicago is sentenced to 105 years in prison for a series of bizarre robberies and sexual assaults. They all take place in women's beauty shops. Willis proclaims his innocence. It is not until 1998 that a committed young US attorney and sophisticated forensics by a Toronto lab uncover a serious miscarriage of justice.

Now a Toronto newspaper writer, Turnbull tells her own dramatic story.

The beaten and frozen dead body of a missing man is found in his abandoned car in Ottawa. The suspects are his wife and/or two male tenants.

Is Michael Giroux a sexual predator and the notorious High Park rapist?

The body of a cocktail waitress is found in a dumpster in Vancouver shot and burned beyond recognition. Detectives follow a maze of clues to the likely killer.

Only he can get to the root of the dilemma to close the case.

A young female taxi-driver is fatally stabbed and left to die in Banff. The investigators find a knife and blood in the abandoned cab. Hundreds of men are questioned and give blood samples in a cross continent manhunt. It is two years before police identify two suspects who refuse to co-operate. It will take undercover operations to get the DNA samples and put a killer behind bars.

A woman goes missing in Summerside, PEI. The blood inside her abandoned car tells a terrible story. DNA confirms the blood on a splattered man's jacket matches that of the missing woman.

Disguised bandits fell a Brinks guard in Oshawa. The police find a fake bomb in the abandoned getaway car. It is a major forensic clue in tracking the gang.

Just days before the trial, investigators get a break, putting them knee-deep in swampy water searching for the murder weapon.

Firefighters find two dead bodies on a burning boat in Sydney Harbour, Vancouver Island. Another boat has been broken into. The assailants may have drunk beer from the discarded cans on the boat. A forensics ID unit matches the cans through a serial code on the lid. Whoever broke into the second boat also killed the couple on the burning boat.

A forensic anthropologist determines the three victims are female and aboriginal, all killed in the same time frame. The victims are identified through a police artist's reconstruction drawings. Behavioural profiler Ron MacKay helps nail a brutal serial killer.

A middle aged Vancouver barber is having remarkably bad luck with his girlfriends - they kept dying. Coincidentally they were all native and alcoholics, so it is some time before an astute pathologist questions the staggeringly high blood alcohol levels.
