A large forest fire has started. Lots of the Pokémon that lives in the forest are scared and want to escape. A Celebi comes from the sky to help put out the fire. It begins to glow and flies down towards the danger. Celebi flies past the fire and the trees begin to get swallowed with thick vines. The fire gets smaller and smaller, when soon it completely dies out. The vines disappear and the forest is back to normal. Celebi manages to catch its breath and it stops glowing. However, one there's a small flame on one tree. The tree begins to tip over towards Celebi. Celebi sees this and it disappears with a flash of light before the tree can squish it. The other Pokémon stare at the tree hoping that Celebi survives. Rain falls down and Celebi teleports to safety. Celebi's eyes are closed and vines begin to surround it.
Ash and co. walk towards the Battle Pike for Ash's next symbol. They come to Cycling Road. Officer Jenny is there guarding it. Brock automatically falls in love with her. Officer Jenny points to the path for walking since they don't have bikes. Pikachu senses something and it heads off in the forest. Ash and co. runs after it. Suddenly, a Pokémon Ranger and her Plusle pops out and blocks their path. Ash asks the Pokémon Ranger if she has seen Pikachu. The ranger picks up her phone and begins to talk into it. When she's done, Ash and co. introduce themselves to the ranger. Brock quickly takes the ranger's hand, but Max pulls him away. The ranger introduces herself as Hinata.
Pikachu continues to run in the forest as it's trying to look for something. It runs right past Team Rocket who's stuck in the vines. Team Rocket is struggling to get out of the vines. Wobbuffet pops out and it squishes Jessie against the vines. Ash and co. comes to the same forest too. Ash rushes in the forest to find Pikachu. Hinata tells them about Celebi. Then she gets out a small device and points it at three Linoone. She closes up the device and a small spinning top flies out of it. Her device then transforms into a remote control. The top surrounds the Linoone, and Hinata begins to control the top with her remote. The top closes in the Linoone. Hinata has successfully captured them. Then Hinata orders the Linoone to break the vines. The Linoone clears the path and Ash and co. continues find Pikachu.
Pikachu looks around, and it finds an injured Celebi lying on the ground. Pikachu decides to help Celebi, so it runs down and talks to it. Celebi slowly opens its eyes and stares at Pikachu. It smiles and falls back down again. Pikachu is worried and it starts to sniff around.
Hinata talks about Celebi some more. The Linoone clears the path with its claws. They approach Team Rocket. Team Rocket wants Ash and co. to help them out. Hinata orders Linoone to set Team Rocket free. Linoone gets up and it slashes the vines open. Team Rocket thanks them and they run off.
Pikachu has found some berries and it offers them to Celebi. Celebi takes a bite out of the berry. It smiles at Pikachu and likes the taste of the berry.
The Linoone runs away, and a Diglett and Dugtrio appear from the ground. Hinata fires her spinning top at the Diglett and Dugtrio. She gets out her remote. The top starts to spin around the Diglett and Dugtrio. The top closes in the Pokémon. The Pokémon digs up a deep hole, and Ash and co. jumps into it.

Suddenly, the Diglett and Dugtrio burst from the ground near Pikachu and Celebi. Hinata comes out too. Pikachu blocks her way towards Celebi. Then Ash comes out and Pikachu jumps into his arms. Max is amazed at Celebi. May looks up Celebi in her Pokédex. Celebi stares at them and accepts them as its friends.
Late at night, Ash and co. stay awake to watch Celebi. The next day, Ash and Pikachu wake up at the sound of Celebi. Celebi is happily flying around the area. Its wounds are all healed. With each passing moment, the vines begin to disappear. The forest sparkles while Celebi absorbs in the light. Suddenly, a mechanical claw reaches out and captures Celebi. Team Rocket pops out of their machine. They recite their motto once again. Once they are done, Team Rocket slowly drives away.
Hinata runs off to rescue Celebi. She jumps on a tree and swings off it. She uses a vine to swing from a tree to the next. Then Hinata jumps onto Team Rocket's machine. Everyone is impressed with Hinata's actions. Hinata jumps onto the mechanical arm. Meanwhile, Plusle thundershocks Team Rocket. Hinata pulls on a part of the arm and Celebi escapes.
