CORPORATE MONSTER | Omeleto

After losing his job, a man is prescribed experimental pills that make him see the people around him as monstrous creatures secretly running the world. His girlfriend tries to talk him back to reality, but the film never quite lets us decide whether he's hallucinating or finally seeing clearly.

Why it's free: Free on Omeleto's own channel; the distributor licensed it from writer-director Ruairi Robinson.
