Acid Row. The name the beleaguered inhabitants give to their 'sink' estate. A noman's land of single mothers and fatherless children - where angry, alienated youth controls the streets. Into this battleground comes Sophie Morrison, a young doctor visiting a patient in Acid Row. Little does she know she that is entering the home of a known paedophile... and with reports circulating that a tormented child called Amy has disappeared, the vigilantes are out in force... Soon Sophie is trapped at the centre of a terrifying siege, with a man she has come to despise. Whipped to a frenzy by unsubstaniated rumour, the mob unleashes its hatred. Against authority... the law... and the 'pervert'. 'Protecting Amy' becomes the catch-all defence for the terrible events that follow. And if murder is part of it, then so be it. BUT IS AMY REALLY MISSING?
