This is a new film that is supposed to be released august 14th. It is basically about aliens settling on earth and the conflict between humans and non-humans.
here is the trailer.
Spoiler: this is the movie short it is based on that will explain things a bit more.
seems to me like is more on the theme of the TV series "Alien Nation". Can humans co-exist with non-humans?
one of themes of the show is that the aliens are trying to take over the planet and steal the resources as they are essentially refugees. However they are not doing it in an overt nature, they are in fact acting like locus but act subservient to local authorities to prevent direct confrontation. Could it be thought of like muslim immigration in europe? Or Mexican immigration in the US?
