Plot summary
Henry targets Holly's classmate and bully, Derek Turnbow, as his next victim. Hopper and Eleven fail to break through the massive wall and are ambushed by soldiers, but manage to overpower them. Hopper and Eleven interrogate Akers, concluding that Dr. Kay is holding Henry at the base. Will, Nancy, and Mike inform the group that Henry lured Holly by claiming he was her imaginary friend, prompting them to devise a plan to use Derek as bait to trap the Demogorgon, and implant a tracker in it to reach Holly before more children are taken.
The group arms themselves using weapons smuggled in by Murray and enlists Erica to drug Derek and his family. The team splits up, transporting the unconscious family to an abandoned barn while converting Derek's house into a trap for the Demogorgon. The plan unravels when Derek wakes up and Will realizes the Demogorgon has located his group. Meanwhile, Holly finds herself in Henry's childhood home. In the nearby forest, she encounters Max.
