Ayrshire policewoman Shirley McKie suffered the loss of her job, a trial for perjury, a breakdown in her health and had to undertake a nine-year campaign before she cleared her name and triumphed over a supposedly infallible science. Her crime - to speak the truth and refuse to accept the mis-identification of her fingerprint, allegedly found at a murder scene she should not have entered. During those nine years, her case became an international cause celebre during which she gained the support of the world fingerprint experts community and much of the world's press whilst at home being persecuted by government ministers, smeared by senior police officers and having her integrity traduced by Scottish forensic experts and Scottish politicians.

Now, for the first time the true and authorized story of the Shirley McKie case is told by her father Iain - her strongest champion - and former MSP Michael Russell who has worked alongside the McKie family for over seven years.
