Dirty (2005) - Region 1 DVD

Having been a gangbanger at only 10 years old, Armando Sancho (Clifton Collins, Jr., Capote) always found acceptance in being a part of a group. The only thing better than king of the street? ' a gangster with a badge. Recruited into an undercover, rogue anti-gang unit of the LAPD at only 28 years old, Sancho brings his street smarts into the force that he swore to protect.

But the line between loyalty and protection becomes blurred when one night on a routine investigation, Sancho's partner Salim (Gooding) kills an innocent man. Unable to deal with his partner's actions and haunted by his conscience, Sancho agrees to testify against his superiors regarding the ongoing criminal enterprises of his squad in exchange for immunity for the murder.

As the hours wear on, Sancho's resolve begins to fade. The IA agents inform him his deal is off unless he can also bring in his partner to corroborate his testimony. Faced with a seemingly impossible task, Sancho realizes for the first time the enormity of the decision he has made.
