But somehow, you get pulled into it anyway, into the darkness that is Hawkins, into something you were never supposed to see. And through all of it, there's Steve Harrington, your sister's best friend, the one person you can't stand. At least, that's what you tell yourself. But as everything around you begins to unravel something between you and him becomes impossible to ignore.
