The summer of 1985. Hawkins is blinded by the neon glow of Starcourt Mall, but beneath the consumer paradise, the Mind Flayer has returned to build a grotesque flesh-army. Meanwhile, a secret Soviet base deep underground works to rip open the Gate. With Eleven’s powers failing and the monster closing in, our scattered heroes must converge on the mall. As Fourth of July fireworks light up the night, the final battle looms—demanding a heartbreaking sacrifice. To close the Gate, they'll need everyone standing together, one last time.
