The prison movie setup..
Main character gets charged with something he or she didnt do or was framed,judge sentences them while the family is shown crying in the background..
When they get to the prison,after the strip search and conversation with the warden("This here is
MY prison,you will follow the rules etc") then theres the"walk to the tier"part where all the prisoners be cat-calling or saying things like"Im'a get you in my cell!!!",the main character ends up in a cell either by himself or with a older cellmate who teaches him the ways of surviving,he then tells him about the various prison gangs(the Mexicans who end every other sentence with "ese" "vato" or "cabron" the racist Aryan skinhead types,the Bloods/Crips-type gang featuring the big brotha who"runs the tier",the gay drag queen inmates etc,as well as the lead CO who you know is a racist thug straight away)
Theres also the one inmate(usually a scrawny White guy) who's like"I shouldn't be here"or is about to be released in like two or three days..on the last day he is packing his things then the warden tells him there was a mix-up and he'll be staying for a whole other year..the inmate snaps and tries to kill the warden but gets beat down by the COs and dragged off to solitary,we dont see him again for the remainder of the film
Towards the end is when the big riot breaks out as a cover for when the characters try to escape,this results in all the supporting characters getting gunned down while the main guy is saved at the last minute after hearing they caught the person who framed him in the first place
