Then the unsettling, ambient music kicks in. It's music that would make anyone want to watch through their fingers, reaching into you to scrape over your nerves.
Then someone plays a...video.
That's all you're going to get, but keep in mind that this movie is not what you would expect it to be. It's labeled as a "thriller" at Netflix--a psychological thriller to be exact. Scenes build upon one another, and every time the hero says (or gives a look that means) something is wrong, we all go one step closer to the abyss.
Not a fun scare, but a deep one.
