A hyperactive jolt of anarchic adrenaline, this mind-bending mash-up of sci-fi, horror, and psychological drama careens from darkly funny to shocking to heartbreaking with whiplash-inducing bravura. Convinced that evil aliens are infiltrating Earth in the guise of human beings, a possibly deranged amateur ufologist (Shin Ha-kyun) kidnaps a powerful businessman (Baek Yoon-sik) in hopes of exposing him as an extraterrestrial. Is it all in his head, or could he really be the only one who can save the world from destruction? The audacious tonal shifts and reality-shifting narrative gambits fly fast and furious in a one-of-a-kind genre-bender that is, ultimately, an urgent, heartrendingly humanist message in a bottle for our fragile planet.
