Ed's dying to see the newest sci-fi reject flick, Robot Rebel Ranch. But, of all the horror, it's R-rated, and the Eds won't be able to get in! They immediately begin scamming to sneak in, but on the way to turn in some recyclables for ticket money, they get lost and wind up way beyond the construction site and the factory, in the worst place to get lost — the junk yard.
The Eds all have new clothes, but they're still stiff from the store. Ed and Eddy try to get them comfortable, but end up ruining them. The Eds find Rolf, Jimmy, Jonny, and Plank wearing spiffy scout uniforms. Rolf tells them about the Urban Rangers, and that they can get their own uniforms if they can get a badge.
Ed can't sleep so he goes to Eddy's house and starts irritating Eddy all night. The next morning they go to Edd's house to find he's taking apart an old radio which somehow leads Eddy to think if knowledge is power then it's also money. The Eds start to take everything they can get their hands on apart.
Eddy tries to convince the kids of the cul-de-sac (and himself) that it is still summer, even though it is actually the day before school starts. At school, the Eds find they've been assigned separate home rooms, and must negotiate with the Kanker Sisters if they want to spend the school year together.
Flashback episode that features alternate stories. The Eds try to make their way back to the place all the flashbacks began. In this journey many things are explained, including: Plank's chip (Plank got stuck in Rolf's teeth), and why Jimmy wears a retainer (the Eds tricked him into eating a bowling pin when he thought it was a cream horn).
Edd tries to take his morning shower, but blunders into the bathroom to find it is undergoing repair. He desperately tries to borrow a shower from one of his neighbors, but as Edd gets progressively dirtier in his quest to find a place to bathe, he eventually goes off the deep end, which means the more nobody would help Edd, the more dirtier he'd be.
The power goes out, and everyone's wondering what happened. Ed starts a panic when he blames the blackout on "mole mutants" (a parody of the C.H.U.D.s and The Mole People), and Eddy tries to cash in. Meanwhile, Rolf enlists Kevin in jump-starting the power grid, and Edd overcomes his fear of the unsanitary sewers to conduct his own investigation.
Edd is embarrassed to no end after losing to Ed in the annual spelling bee. All the other kids think he's lost his touch, and turn to Ed for help with their homework (even though Eddy insists they pay for the privilege). Meanwhile, Jonny seeks revenge on Nazz after she eliminated Plank from the Spelling Bee for not spelling a word clearly.
Peach Creek's football team must play a game against Lemon Brook, but the team is hopeless. Nazz thinks its due to low team spirit, so she decides to make Ed the mascot. During the game, Eddy becomes jealous that the audience is cheering for Ed, not the football team, so Eddy attempts to create a mascot of his own.
The Eds, Kevin, Rolf, and Jonny all make bets who can put off their annoying habits the longest. Eddy must stop talking in a loud voice, Ed cannot have any gravy, Double D must stop talking using complicated words (words with more than one syllable), Johnny must go on without Plank, Kevin has to stop calling the Eds "dorks", and Rolf must stop eating meat. The winner will win $1.25.
Jimmy dreams that an alien space ship invades the cul-de-sac and carries it away. After Jimmy wakes up, it appears that his dream is coming true when Jonny states to the kids that aliens have invaded the cul-de-sac and are at Rolf's house. No one but Jimmy believes him at first, but shortly after Jonny's announcement, a meteor/egg launches from Rolf's chimney and it hatches, leading everyone to believe the tale that Jonny has told them. It is up to the kids of the cul-de-sac to save their pal and drive the aliens away.
The Incredible Shrinking Day is a music video starring the Eds who are shrunk by a potion made by Sarah who puts them in a doll house. The Eds eventually escape and return to regular size. The animation of the music video is notably different than the regular animation. The song featured in the music video is "I'm Not Coming In Anymore". The song is written by Stuart Hill and performed by Garrett Freireich
