Stranger Things is a science fiction-horror series set in the 1980s about a group of friends in the fictional town of Hawkins, Indiana, who uncover a secret government lab, a parallel dimension called the "Upside Down," and terrifying supernatural creatures. When a young boy named Will Byers goes missing, his friends, mother, and the local police chief embark on a quest to find him, which leads them to a mysterious girl named Eleven with psychokinetic abilities. The show is known for its blend of 1980s nostalgia, suspense, and horror, drawing inspiration from the works of Stephen King and the films of Steven Spielberg.
