How do i write about conflict in a prison?

For an English essay i have to write an 1000 words piece of writing on conflict in any form, they are mainly looking for creative writing skills but i need an idea on what kind of conflict i can write about. I need a plan so like first 500 words is for one dilemma so basically needing four main things to happen to do with conflict and is this good for giving me lots of chances to use creative writing skills like pretend someone got locked up in my conflict story and i wrote "the walls, as blank as a so and so were closing in up on me"
