To clear things up, Equilibrium is about a society where emotion is criminal. It follows the story of Tetra Grammaton Cleric John Preston, in elite arm of the law who is expert in the Gun-Kata. I don't want to say more, as to not spoil the plot. But the gun fights are freaking awesome.
It's about a what happens in after WWIII (so it's in the future ) and a man is I think hired to assassinate the president of Libra or something like that.....I just paid attention to the fighting scenes
