With the tagline "From Russia with love," Netflix's teaser for Stranger Things' upcoming fourth season gives fans a reveal that will warm their hearts. We don't know exactly where this season is going yet, but part of it will be set outside of Hawkins, Indiana. We expect to return to Hawkins to catch up with the kids, but it looks like we'll be spending some time in Russia as well. There's also that pesky Upside Down that will probably become a factor again. The teaser sadly doesn't give us the one thing we want most: a start date.
