Warning: Sci-fi/horror movie.

From Omeleto:

After losing his jobs, an unstable man goes into a spiral of depression. His doctor gives him some pills to treat his condition, though they’re “not quite FDA approved yet.”

But after taking the pills, he begins seeing things: he sees people as horrendous monsters, creatures that control the world from the shadows and stay hidden by people’s own blindness and apathy.
