Over a period of two years, eight people, including children, have been brutally murdered in Lanarkshire, Scotland. Detective Inspector William Muncie is in charge of the investigations and knows who did it - Peter Manuel, a man who only recently was released from prison after serving a nine-year sentence for sexual assault. However, he doesn't have enough evidence to convict Manuel, especially as his father always provides an alibi, and Manuel always seems one step ahead.
