District 9 plays in an alternate timeline where aliens made first contact 30 years ago. The unusual is that they were refugees and the last survivors of their kind. They’ve been held in Johannesburg’s District 9 for the last 30 years until humanity decides what to do with them. So far, aliens refused to share their technology with mankind which is why a private company (MNU) is now given control over District 9. But MNU couldn’t reveal the secrets of the alien’s weaponry because it can only be activated by alien’s DNA. Things get complicated for an MNU agent when he gets infected with a virus in District 9 that alters his DNA and makes him the key to the alien’s technology and therefor the most wanted human being on earth.
