A USB stick containing key information about the production and supply of illegal drugs is found in a raid of a respectable businesswoman’s house. Authorities tell police that packages being posted labelled as so-called ‘legal highs’ are a front for dealing narcotics online, so detectives set about finding the factory manufacturing them, before setting their sights higher. Elsewhere, after seeing an increase in guns designed to fire blanks converted into deadly weapons, police target the man responsible.
