Looking for a specific Netflix show from around 2019
I've been looking for a show I had watched at this time but can't remember the name. The main character was a girl and she lived in this poor city under better one that was over a cliff. there was also a sand tornado I think that broke a lot of things in the poor city. to get to the better place, people had to do challenges in a sort of closed building. at the end after the girl wins there's a plot twist which is that to get to that better place, people must get sterilized.
