Elysium (2013)

In 2154, two classes of people exist: the very wealthy, who live on a luxurious space station called Elysium, and the poor, who live on an overpopulated, devastated Earth. While residents on Earth are policed by ruthless androids, Elysian citizens live in comfort and safety, surrounded by robotic servants. They regularly use man-sized medical devices in their homes that keep them free from disease (so called Med-Pods).
Max Da Costa, a former car thief and parolee, lives in the ruins of Los Angeles and works on the assembly line in one of the robotics factories of Armadyne Corp., the company that provides the space habitat, robots, and most of Elysium's weapons. Max grew up as an orphan and has spent much of his life in prison. After an altercation with a robot officer results in a broken arm, he reconnects with a childhood friend, Frey, who works as a nurse in the rundown County Hospital. Frey's daughter Matilda is dying of leukemia.

When a caravan of illegal immigrants from Earth attempts to reach the space station, Elysian Secretary of Defense Jessica Delacourt activates vicious mercenary Kruger , who works on Earth as a sleeper agent, and orders him to shoot down the shuttles in a covert mission. Disapproving of her methods, Elysian President Patel reprimands her, and Kruger is fired. Delacourt, vowing to protect Elysium and her own power, convinces Armadyne's billionaire CEO John Carlyle  to write a program that can override Elysium's central computer and make her President. In return, she offers to guarantee renewal of Armadyne's defense contracts for the next two hundred years. Carlyle agrees to the coup, and after creating the program in his office on Earth, he encrypts it and uploads it to his brain for safekeeping until his return to Elysium.--Wikipedia
