Nick and Gethin have been friends since they were kids, The play hinges on a social experiment being carried out by young filmmaker Gethin. Fascinated by the mass hysteria that attends paedophilia, he asks his sister Sarah to spread rumours about him and proves that the accused is now guilty until proven innocent. Needless to say, it all goes horribly wrong, and Perve is at its most compelling when Gregg (writer) begins to suggest that Gethin may not be as transparent as he seems.
