You (16), Finn Wolfhard (16), Raegan Revord (17), Walter Scobell (15), Ian Armitage (15), Aryan Simhadri (17), Leah Jeffries (15), and Noah Schnapp (16) are all having a sleepover. You all know each other because you're all child actors.

It's late and everybody's asleep...Or so you think. But Finn's awake.
