Colors (1988)

Two white cops, Bob 'Uncle Bob' Hodges - a respected, 19-year LAPD veteran and rookie officer Danny McGavin are partners on the LAPD's gang crime division. Bob had hoped to spend more time with his family, but he's pulled back into active service because of a step-up in gang activity. He makes no secret of his contempt for his novice partner Danny, but eventually comes to rely on the younger man as a valuable street contact.
