SYNOPSIS
An unknown tagger begins to paint graffiti around London, and claims to have been responsible for killing a celebrated street artist four years previously. Originally part of a gang, the victim went solo after receiving support from a wealthy art patron, and when the detectives re-open the case, they become suspicious of his resentful former crew members. Meanwhile, Brian signs up to a social networking site as TopCop999 to chart the gritty life of a lawman, much to his colleagues' displeasure.
