Now that he's received a badge from the Rustboro City Gym, Ash is ready to leave Rustboro and head off to Dewford Island for his next gym battle. May has other ideas. She is thrilled to finally be in a big city and wants to do some shopping. Brock agrees, so they decide to stay. Meanwhile, Max is in a state of panic. He accidentally spilled his drink into May's PokéNav and it looks broken. He gets a tip from a strange old man to take the PokéNav to the Devon Corporation building. The man says that since they manufacture the device, they might be able to fix it. Desperate to avoid May's wrath, Max decides to go for it. Once inside, he learns that the strange old man is actually the president of Devon Corp! Max is really excited by all of the interesting projects the company is working on – but it soon becomes clear that there's in an intruder in the building who is after some of those experiments. Ash and crew arrive just in time to help Officer Jenny catch the intruder, but it's actually Team Rocket who end up saving the day! (thetvdb.com)
