Limerick - A Tale of Two Cities reveals a schizophrenic reality in which Limerick and its people push ahead with progress and development while the ferocious hatreds of feuding gangs continue to play out around them. In the Limerick underworld, Prime Time Investigates uncovers a backdrop to these feuds that’s all about business – the drugs business in particular. It examines gangs it hears described as `mini mafias` and their increasingly businesslike approach to crime and murder. The result - a clash between society and organised crime.
