Unfortunately, the plot of Season 12 of "American Horror Story" is at this point unknown. This makes sense, considering the normally secretive production of the series. The show likes to release exceptionally vague teasers filled with intense imagery, but usually, little plot is ever revealed, if at all. The most recent season is grounded in real life with very few supernatural elements in place, although this is a rare occurrence in the series that is usually rife with ghosts and other such extra-planar beings. The teaser for Season 11 on YouTube features leather, spikes, latex, and partying, and the actual plot is about the AIDS pandemic, so even trailers can be misleading.
That being said, we can probably assume that Season 12 will either channel real-life events or be an absolute ghost-filled romp; it seems like there are two general flavors of "AHS" seasons and it really depends on the writers. One end of the spectrum is populated by the "AHS: Cult" and "AHS: NYC" seasons, while the other end is pretty much all the rest. However, fans may actually get a chance to see both types, as the series has already been renewed for Seasons 12 and 13. According to Newsweek, FX Network chairman John Landgraf released a statement on the continuation: "[Ryan Murphy and Brad Falchuk] are the undisputed masters of horror TV, having created the anthological limited series with 'American Horror Story' and sustaining its success for nearly a decade as FX's highest-rated series."
