After defeating Team Plasma, Ash decides to return to Kanto and Iris and Cilan decide to come with him, so they can still pursue their goals to become Dragon Master and Pokémon Connoisseur, respectively. Professor Juniper offers them a cruise around the Decolore Islands. However, Ash and company get tricked by Team Rocket to their abandoned ship, so they can lock them up and steal their Pokémon...
After Ash is woken up by Pikachu's Thunderbolt, he remembers hes back in Nuvema Town. Ash and friends just got back from stopping Team Plasma from controlling Reshiram. Meanwhile, Team Rocket goes on to tell Giovanni how they stopped Team Plasma in Unova. They love how Giovanni congratulates them for stopping Team Plasma, so they decide to continue their plans to catch Pikachu for him. As Ash and friends sit down for breakfast, they talk about being tired from stopping Team Plasma. Professor Juniper asks Ash what he plans to do next. Ash says he wants to go back to Kanto to tell Professor Oak all about his journey through Unova. Iris then realizes that their journey together is slowly ending and that now she must think about what to do next. Iris then says she wishes to go to Kanto with Ash to meet Dragon Type pokemon from other regions. Ash accepts and Cilan then says he wishes to travel to Kanto with him as well to become a better pokemon connoisseur. Ash and his friends get excited that they get to travel around more. Professor Juniper then asks them how they plan to get there? She suggests that since he took a plane to Unova, that he take a cruise back. She goes on to tell them about the Decolore Islands and that theres a lot of different pokemon there. Ash then accepts to go on the cruise to Kanto.
Team Rocket then plans to catch Pikachu before they go on the cruise. Ash then contacts Professor Oak to tell him that hes taking a cruise back to Kanto. Oshawott then comes out of his pokemon to say hi to Professor Oak. When they get to the cruise ship, Professor Juniper goes to get the tickets. Team Rockets plan then unfolds by James bumping into her as she walks out of the building. She drops the tickets and James switches them for fakes. Ash and friends then say goodbye to Professor Juniper and then they go to get on the ship and their tickets are not accepted. They walk over to another ship where Jessie gets their tickets and accepts them. Jessie then takes their pokemon and pokeballs to the play room, while James takes them to a room. Pikachu and Axew run through the hall, while Jessie tries to keep up. She accidently drops Oshawotts Pokeball, which he then let out. Ash and friends then complain about the room there in and James gets mad. He locks the door so they can't get out of it. Jessie locks the Pokeballs, Pikachu, and Axew in the playroom. Oshawott wandering through the ship then over hears Team Rocket talking about their plan.
Iris then goes to check on Axew and Pikachu to find the door is locked. They try to open it, but it won't budge. Oshawott then falls into the room of Jessie, James, and Meowth and is seen by them. They try to catch him, but fail. Oshawott then damages the control panel of the ship which unlocks all the doors. Pikachu and Axew go to find Ash and the others. Ash finds Oshawotts Pokeball on the floor in which they go to the playroom. Oshawott is then seen cornered by Team Rocket. Ash and his friends then find out that the ships crew is Team Rocket and that now they against them (Previously they helped in the stopping of Team Plasma). Jessie and James send out Woobat and Amoonguss to battle. Iris sends out Excadrill and Pikachu uses Irontail. Excadrill uses dig on the ship and water shoots up. The ship then starts to sink quickly. Jessie and James then try to use their Pokemon to plug the hole, but it doesn't work. Team Rocket then Blasts off and their tickets fall from the sky. Cilan then notices the ship is about to leave and they hurry and run for it. They get on the ship and Porter then welcomes them onto the ship. As the journey continues.
