Rent Colors (1988)

Bob Hodges (Robert Duvall) is a seasoned street cop who has learned a lot from long experience, while his young partner, Danny McGavin (Sean Penn), has learned nothing - and knows it well. Forced to work together in the L.A.P.D.'s renowned C.R.A.S.H. anti-gang unit, they set out to investigate a brutal gang murder. Hated and hunted by both sides, the cops soon find themselves trapped in the middle of a turf war. With nowhere to turn, they are ambushed, double-crossed and shot at in a take-no-prisoners street battle. As the violence escalates, these two diametrically opposed men must come to terms with one important fact - to stay alive they must come together!
