Here’s the official plot synopsis…

“Hawkins, 1959: a regular town with regular worries. Young Jim Hopper’s car won’t start, Bob Newby’s sister won’t take his radio show seriously and Joyce Maldonado just wants to graduate and get the hell out of town. When new student Henry Creel arrives, his family finds that a fresh start isn’t so easy… and the shadows of the past have a very long reach.

“Brought to life by a multi-award-winning creative team, who take theatrical storytelling and stagecraft to a whole new dimension, this gripping new adventure will take you right back to the beginning of the Stranger Things story – and may hold the key to the end.”
