Can you tell what this movie is called?

So I was on a cruise last summer and I decided to watch some tv and I went to a turner channel, I don't remember if it was TNT or turner classic movies. I think at least some of it was in Spanish with subtitles.

Anyways, it was about a family of Mexican brothers and/or cousins. One guy was a Marine, one guy was a drug dealer who shot some people and later a kid (Marines little bro) came in while he was asleep and tried to shoot up, but od'd and died. Then I fell asleep, but when I woke up, a different guy was in prison. Even though he was white, he considered himself Mexican and was trying to earn the gangs trust. He also earned the trust of a white cook named Jim and said that he would suck him off in the kitchen, but shanked him as gang initiation to prove that he was true Mexican. I fell asleep for good after that.

It seemed like a good movie and I would like to see all of it, do you guys know what the title is?
