The Hawkins gang puts together a complex plan to take down Vecna. It involves Eddie (Joseph Quinn) and Dustin (Gaten Matarazzo) going into the Upside Down to distract the bat-like creatures that usually protect Vecna. They enter using the portal at Eddie's house, and the high schooler plays a smashing guitar solo that draws all the bats to the group. Then, they fight the creepy creatures off using their makeshift weaponry.
Job done, Dustin and Eddie turn to head back to Hawkins. But after Dustin crosses over to safety, Eddie realizes that they didn't finish the fight. He cuts the sheet connecting the two worlds in an attempt to keep Dustin safe, then gears up and heads back out into danger.
Eddie ultimately loses, but he creates enough of a distraction to keep the rest of the plan intact. Dustin uses a mattress to cross back over into the Upside Down, and he comforts a dying Eddie.
"I didn't run away this time, right?" Eddie asks Dustin. He also makes Dustin promise to look after the "little sh*ts" in the Hellfire Club as Dustin cries.
"I think it's my year, Henderson. I think it's finally my year," Eddie says, then he dies. Days later, Dustin meets Eddie's uncle and tries to comfort him with memories of Eddie and his death. Dustin tells him his nephew died a hero and was true to himself to the last moment.
