Will Byers and his gang of BMX-riding buddies are back, just in time for Halloween, and Things are about to get even Stranger in Hawkins, Indiana.

It’s now 1984, and Will (Noah Schnapp) and his mum Joyce (Winona Ryder) are still recovering from their ordeal in the parallel universe known as the Upside Down.

But where is telekinetic teen Eleven (Millie Bobby Brown), and what is the shadowy, arachnid-type monster looming over the town?

Sean Astin, who starred in the 1985 film The Goonies, joins the cast for this second series of the sci-fi horror, which stylishly celebrates everything we loved about the 1980s, including the legendary Ghostbusters.

Who ya gonna call?!
