Ahead of the hit show’s final chapter, Netflix has unexpectedly dropped a clip of the opening episode – and a surprise flashback will send chills up spines

The fifth and final series of Netflix’s supernatural smash hit Stranger Things is set to be one of the biggest shows of the year. The first part airs on 27 November, but a clip of the chilling opening five minutes has been shared online.

The episode, The Crawl, takes fans back to the start of the series in 1983, after the disappearance of Will Byers (Noah Schnapp).

“Should I stay or should I go?” Will sings as he tries to keep calm in the Upside Down. Things quickly become terrifying when a demogorgon appears and drags Will to the lair of Vecna (Jamie Campbell Bower). “At long last, we can begin,” he tells Will while shooting a vine down his throat. “You and I, we are going to do such beautiful things together.”

The second part of the concluding series will air on Boxing Day, with the final episode out on New Year’s Day – which will also be screened in select cinemas.
