Netflix has released the second trailer for the highly anticipated series Stranger Things.

The show stars Winona Ryder (Joyce Beyers), Matthew Modine (Dr. Brenner), David Harbour (Chief Hopper), Charlie Heaton (Jonathan Beyers), Natalia Dyer (Nancy Wheeler), Millie Brown (Eleven), Finn Wolfhard (Mike Wheeler), Caleb McLaughlin (Lucas Sinclair), and Gaten Matarazzo (Dustin Henderson), and Cara Buono (Karen Wheeler).

"An innocent night playing Dungeons & Dragons takes a tragic turn for a group of friends in Hawkins Indiana when Will Byers disappears...seemingly into thin air," reads a press release about the show.

"The year is 1983 and this small town is abuzz with conspiracy theories behind the missing boy's circumstances. As friends, family and local police search for answers behind his disappearance they are drawn into an extraordinary mystery involving top-secret government experiments, terrifying supernatural forces and the discovery of one very strange little girl."

It continues, "Her appearance and powers appear super human and the boys begin to understand that she might have a sinister connection to their missing friend. With the debut of an impressive young breakout cast (Finn Wolfhard, Gaten Mattarazzo, Caleb McLaughlin and Millie Brown as Eleven), Stranger Things is a love letter to the ubiquitous cult classics of the 80's."

All episodes debut globally on Netflix Friday, 15 July.
