When Brock falls ill, Ash and Misty must do all of the chores that he normally does. This includes cleaning up after themselves, cooking, getting firewood, and taking of Brock. To make matters worse, Team Rocket is planning on ambushing them to take all of their pokemon.

On the long trek to Olivine City, our heroes notice Pikachu looks a bit worn out. All of a sudden a man named Simon appears and starts talking to Pikachu in pokemon language! He takes them to his rest stop to heal Pikachu. Officer Jenny shows up and claims that Simon is swindling money from trainers. Ash, Misty, and Brock then set out to prove his innocence.
