As creepy as the Upside Down is, perhaps even more unsettling is Dr. Brenner's research lab—a place that Eleven is all too familiar with. Her time in Dr. Brenner's strict program has left an indelible mark on her psyche, and that haunting past (as well as new glimpses into her life) is teased in a new promo video for the second season of Netflix's Stranger Things.
Season 2 synopsis: "It’s 1984 and the citizens of Hawkins, Indiana are still reeling from the horrors of the demogorgon and the secrets of Hawkins Lab. Will Byers has been rescued from the Upside Down but a bigger, sinister entity still threatens those who survived."
Stranger Things Season 2 premieres on October 27th on Netflix. Although Will may be back at home after being missing (and hunted) for most of the first season, things are far from back to normal for everyone who was affected by his disappearance. As evidenced by the Comic-Con trailer below, the Upside Down—and the creatures that inhabit it—is seeping into our own world... with deadly results.
