The heroes came to the Pokémon Center. When they open the doors, a pack of Gastly fly away from the Center. The wander a bit and see nobody. They came to a room and see dinner. Ash goes to get it, but a child comes and accuses him of stealing, then hits him with a broom. They explain they did not want to steal anything and Nurse Joy and another, similar kid, appear. The child with the broom calls Joy mommy and Brock is sad to see a ring on Nurse Joy's finger.
The heroes have a meal. The child apologises for the rude treatment. They want to be just like her mom and introduce themselves as Marnie and Paige. Ash proposes to help them and Dawn and Brock agree. The heroes work for a while and are done. Paige sees dad forgot lunch, so Marnie sends Driftloon to do that. Marnie goes to accompany them and Paige wants as well, but Marnie tells she's too young. Nurse Joy tells Paige she could give the Pokémon in the forest cookies she made instead, so she accepts the task. Marnie grabs the Driftloon's hands and they fly her away. Ash goes with Marnie to give the cookies, per her request.
Paige gave the cookies to the Pokémon and tells Ash she has one more friend, but cannot say her name, as Marnie does not allow her. Still, she shows it to Ash, but sees it is not there. She tells him the friend is Suicune and they play with it a lot. Meanwhile, dad fixed a panel and Marnie arrives with his lunch. Team Rocket spy and want the Ampharos he has. Meowth thinks, with its glow, the boss' nightmares would be away. Marnie gives dad the lunch and dad thinks he should take her home, as a storm approaches. Suddenly, Ampharos gets caught. Still, since they have no money for isolation, Team Rocket get blasted off by a Thunder. However, dad sees the wires had been damaged by the explosion.
Brock and Dawn helped Nurse Joy, while Ash and Paige arrive. Suddenly, the electricity went out and Joy goes to go to the power plant, where dad works. Paige is nerved by the fact mom tells her to stay and goes away. Pikachu follows her to get her. Joy goes on her bike to the power plant and Paige got her Driftloon to fly to the power plant. However, despite Pikachu's strength to pull her down, the wind is too strong and he, along with Paige, got blown away. Dad fixed the turbines, and with Ampharos' electricity, they work again.
The heroes come to tell Paige and Pikachu got blown away. Dad calculates that the wind is blowing in the same direction - to the mountains. Marnie sends the Driftloon and tells she will go to search, but dad does not allow her, as the storm will be any moment. A wind blows and Ash quickly grabs the Driftloon, as he needs to save Pikachu and Paige. The others go in the car to get them. Paige is scared, as she, Driftloon and Pikachu are on a mountain away from others. Dad drives the car and he stops, as the huge boulders stop their path.
Ash and Driftloon came to Paige and Pikachu. He is relieved to see them and tells they should go. Ampharos uses ThudnerPunch, but with no effect. Dad tells Dawn and Brock to wait while they go to search. Marnie leaves and thinks she could help. Ash, Pikachu, Driftloon and Paige found shelter in a cave. Ash tells Paige everyone is looking for them and everything will be in order. Paige runs and has her path blocked by some trees, but continues. Paige came to the lake and calls upon Suicune for help. The rain stopped - Ash and Paige wander through the fog. They stop on a log bridge and see there is no choice but to cross.
Marnie's hope left her and wanted someone to help her. She realizes she is the one that needs to help her and goes, but senses a presence - Suicune arrived. Pikachu crossed the bridge, so Ash and Paige are the only ones remaining. The bridge breaks and they fall, but just then Suicune and Marnie get them. They thank Suicune for the rescue and hear the others. They arrive and re-unite. Marnie tells Suicune helped them, but they see it is no longer here. Everyone leaves to eat dinner. In the night, Team Rocket wander from their last blast off. They spot Suicune and charge to get it, but as always, got blasted off.

- It was revealed that "Joy" is the nurse's family rather than given name. Marnie's full name is Marnie Francis Lynnette Joy, which is Sayaka François Joy in Japan, and Paige's full name is Paige Francis Lynnelle Joy, which is Mai François Joy in Japan). The same may also apply to Officer Jenny, as a young Officer Jenny by the name of Marble would later appear in Luxray Vision!.
- Pokettari Monsutari and music from Lucario and the Mystery of Mew and Destiny Deoxys are used as background music.
- The episode contains many references to the plot and characters of My Neighbor Totoro, with Marnie and Paige being analogues of the movie's protagonists, Satsuki and Mei.
- Nurse Joys are revealed to keep their surname in marriage.
- The name of Paige and Marnie's father is never mentioned in the dubbed version of the episode. The only references to Karsten's name occur in the closed captioning.
