District 9

Ok its about alien staying in earth o.o..
While actually the alien is trapped in earth and located in an area.Their weapon were confiscated turning them into the slump life.Their weapon was taken and experimented by the government organization MNU which they are unable to use,it is uniquely encoded with the alien dna so the MNU is finding way to use it.
Just nice 1 innocent member of MNU is affected by the alien liquid which the alien wanted to use it to return home and is tranforming him into alien which means allow him to use the alien weapon SO the government want to know HOW and some other underworld group and wanna capture him.
of cause im not gonna write the whole story down lolols.
