Stranger Sings!

In a small Indiana town in the early eighties, young Will Byers vanishes and his mother, Joyce, turns her living room into a tangle of Christmas lights in hope of a sign. His friends Mike, Lucas and Dustin set out to find him with the help of Eleven, a mysterious girl with strange powers, while the town's parents and teenagers flounder, a dancing Demogorgon lurks and Barb, the friend everyone forgot, finally gets her moment.
