part 2

Nobody used to notice Frank Lucas (Oscar® winner Washington), the quiet driver to one of the inner city's leading black crime bosses. Through ingenuity and a strict business ethic, he comes to rule the inner-city drug trade, flooding the streets with a purer product at a better price. Lucas outplays all of the leading crime syndicates and becomes not only one of the city's mainline corrupters, but part of its circle of legit civic superstars.
Richie Roberts (Oscar® winner Crowe) is an outcast cop close enough to the streets to feel a shift of control in the drug underworld. . Both Lucas and Roberts share a rigorous ethical code that sets them apart from their own colleagues, making them lone figures on opposite sides of the law. The destinies of these two men will become intertwined as they approach a confrontation where only one of them can come out on top.
