Acid Row is the name given to their housing estate by the beleagured inhabitants; a no-man’s-land of single mothers, fatherless children and angry, alienated youth who control the streets.  Enter Sophie Morrison, a young doctor visiting a patient – and she unknowingly enters the home of a known paedophile – and with reports circulating that a tormented child called Amy has vanished, the vigilantes come out in force. Whipped into a frenzy by the unsubstantiated rumour, the mob unleashes its hatred against authority, the law and the ‘perve’ and a terrible series of events follow, with Sophie trapped in the middle of it all.
