Ur rite wot was in that briefcase??
Haven'e got time to tell the whole story but i'll put the main points of it.
Sum dude's are hired by this irish women called deirdre( can't spell) and they are taken to sum meeting point which will be their HQ. I think they hired this ex-CIA guy (De Niro), this french dude who cud get all the equipment u needed (Jean Reno), this getaway driver dude, sum ex military dude (sean bean), this ex-KGB guy. There not really given much info on the job, there just told that they have to get a briefcase off this guy who's well guarded and armed. There not told who they are, wots in the briefcase etc.
They have to recon the guy with the briefcase - get info on how many guys etc.
They plan to ambush the convoy. They stop at sum traffic lights. Take out the first car, shoot sum guys, the car with the briefcase buggers off, u have to chase - kill dude but ur betrayed by the ex-KGB man who changes the case wit a fake one which is a bomb. KGB guy plans to sell it to the russians etc etc.
