The Upside Down is coming back to Netflix on May 27. Ahead of its premiere, the streaming platform dropped the first trailer for the upcoming season of one of its most popular shows and it features a blue monster that's looking to wreak havoc on Hawkins and, quite possibly, the rest of the world.
The new footage will be the first that fans will be seeing of Stranger Things season 4 since the teaser last year and it's definitely worth the wait.
For those who need a refresher on what happened heading into the penultimate season of Stranger Things, season 3 saw the Upside Down's return to Hawkins. Audiences found out that the city's Starcourt Mall hid a covert Russian military base researching the supernatural. By the time the season had ended, David Harbour's Jim Hopper appeared to have sacrificed himself to save the world. However, as it turns out, Hopper ended up in a Russian prison camp instead. In the meantime, an Upside Down denizen possessed the Mayfield siblings, Max and Billy, with the gang ultimately succeeding in the end.
