In a Nutshell:
A cop undercover in the mafia and a mobster undercover in the force; each struggles to keep their identity while trying to oust the other.
Lies. Betrayal. Sacrifice. How far will you take it?
Frank Costello: 'When I was growing up, they would say you could become cops or criminals. But what I'm saying is this. When you're facing a loaded gun, what's the difference?'
Frank Costello: 'I don't want to be a product of my environment. I want my environment to be a product of me.'
Colin Sullivan (Matt Damon) may appear to be an outstanding police recruit but appearances can be deceiving, so deceiving in fact that he’s also working for the FBI's most wanted; Frank Costello (Jack Nicholson).
They may say there’s no discrimination in the police force but for Billy Costigan (Leonardo DiCaprio) it’s a very different matter; to enter the police he must infiltrate the Irish Mafia as one of their own.
Cats are released and rats are chased but which will be caught first?
The bloodshed and violence increase as each party searches for the mole in their organisation, edging ever closer to all out war.
After the police fail to obtain substantial incriminating evidence to put Costello behind bars, Billy becomes their only hope for success.
In turn, Costello begins to pile more pressure on Sullivan to discover the mole, pushing Billy closer to breaking point.
The lines that separate criminal and cop begin to merge as it becomes a race against time to bring down Costello.
The only question is: can Billy catch Costello before Sullivan finds him out?
