During his 18 years in Folsom Prison, street-gang leader Santana rules over all the drug-and-murder activities behind bars. Upon his release, Santana goes back to his old neighborhood, intending to lead a peaceful, crime-free life. But his old gang buddies force him back into his old habits.

A confident young cop is shown the ropes by a veteran partner in the dangerous gang-controlled barrios of Los Angeles, where the gang culture is enforced by the colors the members wear.
