Thirty years ago, aliens arrive on Earth. Not to conquer or give aid, but to find refuge from their dying planet. Separated from humans in a South African area called District 9, the aliens are managed by Multi-National United, which is unconcerned with the aliens' welfare but will do anything to master their advanced technology. When a company field agent contracts a mysterious virus that begins to alter his DNA, there is only one place he can hide: District 9.

The war against the Bugs continues! A Federation Starship crash-lands on the distant Alien planet OM-1, stranding beloved leader Sky Marshal Anoke and several others, including comely but tough pilot Lola Beck. It's up to Colonel/General Johnny Rico, reluctant hero of the original Bug Invasion on Planet P, to lead a team of Troopers on a daring rescue mission.
