The fifth and final season of Stranger Things has so much going on that multiple story lines needed to be clarified off screen. Created by Matt and Ross Duffer, Stranger Things focuses on a fictional town where a series of supernatural events take place, causing mystery, death and mayhem. The hit Netflix series catapulted its cast members - Finn Wolfhard, Noah Schnapp, Millie Bobby Brown, Gaten Matarazzo, Caleb McLaughlin, Natalia Dyer, Charlie Heaton and Joe Keery - to stardom after it premiered in 2016.
