Dark Blue - Season 1 (2009)

Dark Blue takes place in the underbelly of Los Angeles, where criminals roam free under the veil of night or hide in the shadows of day. Wandering in and out of this seedy underworld is commonplace for Lieutenant Carter Shaw (Dylan McDermott) and his special undercover task force. This team understands, better than anyone, that to bring down a criminal, one must first get on their level.
