Unfortunately, the plot of the 12th season of “American Horror Story” is still unknown at this time. This makes sense given the normally clandestine production of the series. The show likes to release exceptionally vague teasers full of intense imagery, but little, if any, of the plot is usually revealed. The final season is based on real life with very few supernatural elements, although this is a rare occurrence in the series, which is usually full of ghosts and other such extra-planar beings. The teaser for season 11 on YouTube features leather, spikes, latex and parties, and the actual plot revolves around the AIDS pandemic, so even trailers can be misleading.
That being said, we can probably assume Season 12 will either channel real events or be an absolute ghost 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 seasons AHS: Cult and AHS: NYC, while the other end includes pretty much everything else. However, fans might actually get a chance to see both guys 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 sequel: “[Ryan Murphy and Brad Falchuk] are the undisputed masters of horror television who created the anthological limited series ‘American Horror Story’ and have maintained its success as the top-rated FX series for nearly a decade.”
