Glenn Plummer delivers a powerful performance in this angry film based on Crips, a novel written by South Central Los Angeles high school teacher Donald Baker, and directed by Steve Anderson, who served time in prison. Plummer plays Bobby, a young black man trapped in a self - perpetuating cycle of hatred, incarceration, and bloodshed. On his first day out of prison, he comes back to the streets of South Central LA and the only family he knows - the gang.
