After being abducted by aliens during a technology-free camping trip, a group of college students discovers that they're all pregnant. A desperate appointment at the gynecologist ends with them waking up at Area 51, where the four young adults slowly realize they're part of a human-alien breeding experiment.
By "The Future Perfect," Troy Lord (Isaac Cole Powell), Cal Lambon (Nico Greetham), and Jamie Howard (Rachel Hilson) have given birth to botched hybrids and die shortly afterward. Kendall Carr (Kaia Gerber), the last member of the friend group to go into labor, produces what Theta (Angelica Ross) deems the perfect specimen.
The aliens have been working toward this human-alien hybrid for decades, and now that it's finally here, what's next for them? While some "American Horror Story" fans questioned Theta's role at Area 51 and dismissed the aliens as hypocrites, their reign over the human race couldn't be stopped — even with Mamie Eisenhower's (Sarah Paulson) last-minute rebellion.
Cloned and essentially lobotomized, Kendall becomes an incubator for the aliens to rapidly reproduce before they begin wiping out the human race. The finale of "Death Valley" is left open, with Calico (Leslie Grossman), promoted to being a stand-in mother, gently holding Kendall's second baby. It's unknown whether or not the remaining humans at Area 51 will be killed, or if some will be recruited to help with the takeover.
