Elysium is a movie about a place called Elysium, which is super fancy and nice in space, where rich people live. It has everything anyone could ever want like beautiful gardens, giant mansions, and lots of fancy cars. It's a lot like the coolest amusement park ever made, but way bigger and fancier.
On the other hand, there is a place on Earth called Los Angeles, which in the movie is really crowded and polluted. People are always sick and hurt or hungry there, and there's not much anyone can do about it. The people who live there are called "normal" people because they're not as rich as the people who live on Elysium.
The story is about a man named Max who lives in Los Angeles and is just a normal guy. Max is really sick because he was exposed to bad stuff at his job (working in a factory), and he needs to get to Elysium to be cured. But he can't because only rich people can go to Elysium.
But Max has a plan. He decides he's going to try and get to Elysium by sneaking in. He meets a girl named Frey, who he grew up with, and she has a sick daughter who also needs to get to Elysium. Max agrees to help Frey get her daughter to Elysium in exchange for Frey helping him get there too.
Max and Frey's daughter go to Elysium and get fixed up by a magic medical machine, but then they get caught by the mean people who work on Elysium. Max fights them and saves Frey's daughter, but he gets hurt really bad. In the end, Max dies, but he saves the day by changing the rules so that normal people can go to Elysium too.
In conclusion, Elysium is a movie about a fancy place in space that only rich people can go to and a normal guy from Los Angeles who tries to go there to get cured of his sickness. He meets a girl and helps her daughter get cured too. Max saves the day by changing the rules so that anyone can go to Elysium.
