On the Down 'n Low (2003)

Most cops start at the bottom and work their way to the top, but in this heated urban crime thriller the officers sworn to protect and serve walk a dark path of corruption and destruction as they gradually succumb to their deepest criminal instincts. When two decorated police officers pound the pavement on a mission to take down the most vicious mobsters and drug dealers on the streets, their quest to purify the corrosive cesspool of a city they call home soon leads them into the upper-most ranks of the force.
