The first season of Netflix's horror hit focused on the mysterious disappearance of a small boy, Will, to a place inbetween worlds called 'Upside Down'.

The second season is set a year later. In a series description, Netflix says: "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."

The entire series will be available to watch on October 27.
