Just had this stroke of brilliance while I was listening to the soundtrack. Anyways, the story...(This'll be short and to the point.)

Dummer, New Hampshire. 1993

A group of three kids wandered through the forest. Now they're gone. Police say that they got lost inside of the woods, but their friends suspect something different. Something more dangerous. They aren't alone. But they will have to solve this mystery...or die trying.  

Now, there will be a monster somewhat similar to the Demogorgon. And the kids will be the ones who have the most knowledge about it. But when we start out? We will have no clue whatsoever. There will only be a designated number of kids. Somewhere close to three or four. As for high schoolers? I don't know. It goes any way for them. As well as adults. There will be a slight government conspiracy, but not like Hawkins Lab. More like the government covering all of this up. 

Now, if there's anything else you want to know, ask me. As I promised, this was pretty short and to the point. I think.
