A clip from season 5 shows some characters in Stranger Things moving through what looks like an underground bunker. This may imply that they are under government supervision after the situation spiraled out of control in the season 4 finale. It will be interesting to see how this development impacts the story in season 5.

The fifth and final season of "Stranger Things" will be released in the fall and will have a three-premiere roll out. Volume 1, which will include the first four episodes will be available to stream on Netflix on Nov. 26. On Christmas Day, Dec. 25, Volume 2 will premiere with the next three episodes. The finale will arrive on New Year's Eve.

The official teaser trailer for Season 5 previews a final battle with Vecna, whose complex origin story is the focal point of the play "Stranger Things: The First Shadow."
