The 80s inspired sci-fi show, created by the Duffer Brothers, follows the residents of Hawkins, Indiana, as they struggle to uncover truth behind a series of supernatural happenings occurring within their previously quiet town.

The new series tagline, ‘We’re not in Hawkins anymore’, suggests that Stranger Things will explore The Upside Down in a new location.

The post-credits cliff-hanger in the most recent series finale hints at the direction the fourth series might follow. In a prison in Kamchatka, Russia, the original Demogorgan monster from the first series returns to torture prisoners.

A Russian guard mysteriously refers to an unseen inmate as ‘the American’, which suggests that the identity of this prisoner will be a crucial part of series four.

The streaming platform have also signed a multi-year deal with the show’s creators to produce films as well as more TV series.

Speaking on the successful deal with Netflix, The Duffer Brothers commented: “We can’t wait to tell many more stories together -- beginning, of course, with a return trip to Hawkins!"

Ted Sarandos, the Chief Content Officer at Netflix, said: “The Duffer Brothers have captivated viewers around the world with Stranger Things and we’re thrilled to expand our relationship with them to bring their vivid imaginations to other film and series projects our members will love.

"The streaming platform have also signed a multi-year deal with the show’s creators, The Duffer Brothers, to create more series and films.”

Series one to three are now available to watch on Netflix.
