Our heroes have stopped at a busy Pokémon Center to get out of the rain when the power goes out! Clemont soon discovers that a leak in the roof has caused a short circuit, and recruits Luxray, Pikachu, and Dedenne to serve as a temporary source of electricity while he fixes it. Ash climbs up to repair the leak, and Serena and Bonnie offer to help Nurse Joy take care of the Pokémon.
Clemont needs a replacement fuse, but he can’t leave the still-sparking fuse box unattended, and everyone else is still hard at work. So he sends Chespin and Bunnelby into town with a note for the shopkeeper! Along the way, the two Pokémon run into Team Rocket...but just as Ash shows up looking for Chespin and Bunnelby, they send the villains blasting off all by themselves!
Eventually, they acquire the new fuse and bring it back to Clemont, who gets the power going again, and all is well...all except for Chespin, who eats way too much at the victory feast and becomes the newly restored Pokémon Center’s first patient!
