In the Brazilian movie Bacurau, inhabitants of the fictional town are shown to be taking some kind of drug, that is later referred to as "a powerful psychotropic drug" by one of the protagonists.
The full quote is:
We have taken a powerful psychotropic drug. And you are going to die.
The drug is administered to someone that returns to the town after being away for a long time right on entry, almost like a kind of vaccine. Later the drug reappears in several scenes, in one scene a fatally wounded person is asked if they want to live or not, and are given the drug when they confirm that they want to live.
I don't really understand the metaphor here, and would be interested in hearing opinions on what this drug is supposed to symbolize, or why the filmmakers decided to make it an element in the story.
