So this guy comes over from Sicily when he was a kid and then he gets in charge of a big mafia gang and the people working for him do a buncha bad things. He's really powerful, and then they cut this horse's head off and leave it in some guy's bed and it scares the crap outta him. Then there's this big shootout at a toll both where they kill the guys son. And the younger son takes over, but he ends up shooting his other brother because of something he did in Cuba. You don't actually see his brother get shot. But you do see the first guy in charge die. He's got an orange in his mouth and he's chasing kids around. Oh, and there's this senator from Nevada who gets blackmailed by the gang.
It was a grate movie. You should see it. Especially the part where the one son shoots the other gangsters in the restaurant. That part was really cool.
