Wanda Maximoff and Vision, two heroes from the Marvel Cinematic Universe films, are living as a married couple in the small town of Westview, NJ, in what appears to be an old-fashioned sitcom (though the era changes from week to week). But there are hints that this isn't their real life, and something very strange is going on. Aside from the main characters, the person we see the most of is their neighbor, Agnes. But Wanda also befriends a woman named Geraldine... who eventually turns out to know the truth about Wanda and Vision (the latter of whom is supposed to be dead). So Wanda casts her out of Westview, beyond a barrier that surrounds the town.
Episode 4 is a major game-changer for the entire nature of the series. It goes back in time a bit to show us events leading up to "Geraldine" entering Westview. Her real name is Captain Monica Rambeau (originally seen as a kid in "Captain Marvel"), and she works for an organization called S.W.O.R.D. (Sentient Weapon Observation Response Division). Her boss, Tyler Hayward, sends her to investigate the disappearance of Westview. Once there, she meets an FBI agent named Jimmy Woo (previously seen in "Ant Man and the Wasp"), and a scientist named Dr. Darcy Lewis (previously seen in the first two "Thor" movies). Darcy discovers a TV signal coming from inside the barrier, so they can watch the sitcom to see at least some of what is going on in Westview. Monica discovers that everything and everyone in the town are being controlled by Wanda (which suggests she somehow has gained powers far beyond what she used to have). Over the next several episodes, the SWORD team continues to try to infiltrate the barrier, while in Westview, Wanda begins losing control, and Vision begins searching for the truth about who he really is.
Beyond that, there are a number of twists I probably won't ever want to spoil in this review, unless I feel it becomes necessary, for some reason. So all I can say for now is I find the show incredibly inventive and intriguing, and I look forward to seeing how it all ends.
