Prison is such a good idea tbh, I can imagine some really creepy ghosts haunting that place!
Mine would be called American Horror Story: Cruise and it would be centred around a haunted ghost ship. Like all my favourite seasons of the show, there'd be two different eras in there - one in the 1910s, when the ship was first made and one in the present day, when there's an anniversary voyage marking 100 years of the ships disembarking. Naturally, the first era would feature James March from Hotel as a mass murderer who kills everyone on board before the ship crashes into an iceberg. The Countess will also appear alongside a young Sister Jude and some of the Freak Show characters who are on there as entertainment. We think March is dead but in the present day, the ice melts and he's revealed to be alive. The current day is based around a murder mystery cruise in which someone pretends to be killed and the other passengers have to find out who did it; but the murders soon start turning real without anyone realising. Connie Britton appears as well as Lily Rabe and Emma Roberts.
Towards the end of the season, the ship crashes again and everyone's left on a deserted island. The remaining passengers now have to deal with the mass murderer from the ship and a new monster who inhabits the island. In the last episode, the remaining passengers are discovered by a ship heading to Russia that takes them on board and rescues them. Sadly, this ship also crashes in the middle of Siberia and the people start resorting to cannibalism. Then, at the end of the last episode a title screen is displayed saying European Horror Story: Wasteland, announcing a spin-off of the show to come next year alongside the normal AHS!
Idk, mine isn't as exciting as yours but I tried.
