Answer the following question: Generate a question that has the following answer: metal flower for the following movie plot: In an alternate 1982, an alien ship inexplicably stops over Johannesburg. When investigation teams enter the ship, they discover a population of sick and malnourished extraterrestrials, who become nicknamed "prawns". The South African government confines the aliens to "District 9", a government camp that is located outside of Johannesburg. Twenty-eight years later, in 2010, following periodic conflict between the aliens and the locals living near District 9, the government hires private military company Multinational United (MNU) to relocate the aliens to a new internment. Wikus van de Merwe (Sharlto Copley), an Afrikaner bureaucrat, is appointed by Piet Smit (Louis Minnaar), an MNU executive and his father-in-law, to lead the relocation. Meanwhile, three aliens Christopher Johnson (Jason Cope), his son, and a friend scavenge pieces of their technology from which they distill a fluid of their native provenance, and store it in a small canister. Wikus confiscates the canister from the shack of Christopher's friend, but accidentally sprays some of the fluid onto his face. Christopher's friend is subsequently killed by Koobus Venter (David James), a sadistic mercenary soldier employed by MNU. Under the fluid's influence, Wikus' body, starting with his injured left arm, begins to deteriorate and become alien tissue. He is immediately detained and transported to MNU headquarters for experimentation, where it is discovered that Wikus' chimeric DNA grants him the ability to use alien weapons, which are biologically restricted to work for alien users only. Realizing the potential fortune to be made from Wikus' tissue in its current state, Smit and his scientists decide to vivisect Wikus; but he overpowers them and escapes the facility. Smit orders Venter and his men to hunt Wikus down, while a smear story is published that claims Wikus has been engaging in sexual activity with aliens and is a fugitive infected by an alien STD. Everyone believes the story, even, for a time, Wikus' wife (and Smit's daughter)...
