Ronaldo is truly in the spirit of spookiness, answering the door in costume. His enthusiasm is somewhat dampened by the presence of Lars, but Steven's eagerness lets him shake it off. Ronaldo goes on to explain the movie they're going to watch, about an evil bear. Lars smirkily disparages this as well, insulting the movie's bad special effects and Conspicuous CG. Ronaldo, offended, informs Lars that the CG is in the remake. They're watching the original, old VHS copy. Sadie is actually excited about this, but worried that the movie will be too scary for little Steven. Steven assures her it will be fine.
Steven does turn out to be fine as he ends up "watching" the movie from behind the sofa. Ronaldo asks if he isn't missing too much and can see okay that way. Lars makes another smirky remark and suddenly the TV goes dead. The kids begin to seek out an explanation, but weird things begin to happen. Ronaldo is frightened, but excited, though his first concern is getting "the civilians" to safety. He's impressed by Sadie's cool head in a crisis, and asks her if she wants to help investigate the haunting.
They get to the ground floor and they're suddenly attacked by a horde of moving scarecrows, with one almost getting at Lars. After some struggle they're able to get them out of the house. Ronaldo accuses Lars of being the cause by attracting the spirit with his jerkassery, Lars demands Sadie to ditch Ronaldo and Steven, because he's sure they're doing all this to mess with him, and that it can't be a real haunting. Sadie refuses, and the floor opens beneath her, swallowing her up. The boys make their way down to the basement, where Steven says something about the house being hurt and angry. On the wall, there's a pulsing, heart-like growth with "Lars" carved into it. Beneath it, a mouth forms, opening hungrily.
Ronaldo picks up Lars and throws him into the house's gaping maw, in hopes that the angry spirit possessing the house will give back Sadie. Steven rushes after Lars, shielding them both with a bubble. The bubble overpowers the mouth and shatters the wall, revealing an unhurt Sadie.
The source of the haunting is revealed: a large black gem that Steven takes into his hands. It plays a hologram from years earlier: Lars and Ronaldo were once friends, and were planning on making the lighthouse their clubhouse. When Lars carved his name into the wooden panel of the wall, the house felt it and struck back at him. Ronaldo happened to catch a photo of it, and when he announced his intention to take it public to prove the truth of paranormal activity, Lars asked to see the photo. Embarrassed at the idea of Ronaldo publicizing him in a moment of vulnerability and uncoolness, he "tore himself out" of the photo, essentially destroying it — and their friendship. The two argue about why Lars cares so much about what other people think of him. Lars counters that Ronaldo should hear what other people say about him. The two part company, their friendship in as many pieces as the photo.
Ronaldo wants to examine the gem more closely, but Steven says it needs to rest, and bubbles it off to the temple. Lars is all the more embarrassed at having his childhood cruelty and vulnerability exposed. Sadie leaves with Steven, as the two figure maybe Ronaldo and Lars want a chance to mend their friendship.
Lars doesn't seem to want to, but the episode decides to Iris Out on his grimace as Ronaldo tells him to take it down a notch.
