In addition to the trailer, we also have a full synopsis for the season (
courtesy of Tutum):
“The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished — his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming — and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone — the full party — standing together, one last time.”
Plus the entire cast:
Winona Ryder (Joyce Byers), David Harbour (Jim Hopper), Millie Bobby Brown (Eleven), Finn Wolfhard (Mike Wheeler), Gaten Matarazzo (Dustin Henderson), Caleb McLaughlin (Lucas Sinclair), Noah Schnapp (Will Byers), Sadie Sink (Max Mayfield), Natalia Dyer (Nancy Wheeler), Charlie Heaton (Jonathan Byers), Joe Keery (Steve Harrington), Maya Hawke (Robin Buckley), Priah Ferguson (Erica Sinclair), Brett Gelman (Murray), Jamie Campbell Bower (Vecna), Cara Buono (Karen Wheeler), Amybeth McNulty (Vickie), Nell Fisher (Holly Wheeler), Jake Connelly (Derek Turnbow), Alex Breaux (Lt. Akers), and Linda Hamilton (Dr. Kay)
Several things to note: We finally know the name of Linda Hamilton's character! I wonder why we don't get her full name...unless that's the only name she has.
Curiously, joining the cast is Alex Breaux, who is currently playing Dr. Brenner in the Broadway version of
The First Shadow. I imagine that's just either a coincidence or a Broadway casting decision made by someone who had seen his performance in this season, although I don't know how directly involved the Duffer Brothers are with either stage production.
Notably absent is Paul Reiser's Dr. Sam Owens. While I'm fine with him not being part of the main cast, I hope he appears in at least one episode.
Lastly, in case anyone needs a reminder (I had to look her up myself), Vickie is the girl Robin had a crush on in the high school band. I can't remember if we knew she was returning or not, but her listing her seems to indicate a significant role. Likewise, it appears, Holly Wheeler.
