Don't be fooled. The title may have the word Misty in it, and there's a girl that sounds like Misty, but it's not Misty.
Ash and co. are set off from Mauville by heavy fog. Soon they notice a lighthouse in the distance. Who does it belong to, and how does it work?
A boy is polishing a stone in the lighthouse, but Team Rocket appears, capturing the child and taking the Light Stone. Team Rocket goes away in the balloon and the boy's sister comes and unties him. The gang is wandering in the fog, so Ash later trips and falls down. Max wonders where the light house is. Suddenly, a woman asks when the fog is going away, to which Ash replies he does not know (subconsciously), but then hears Team Rocket talking.
Meowth asks if the Electric attack will activate the Light Stone and Team Rocket hears Pikachu. Both teams see each other. James sends Cacnea and it uses Pin Missile, but Pikachu uses Iron Tail, deflecting the attack. Pikachu uses Thunderbolt, making the Light Stone glow and Team Rocket blast off. When Pikachu goes off the stone, it turns off.
The boy and his sister appear. The mom mistakes them to be thieves and sends Magnemite to fight. Pikachu uses Quick Attack, defeating Magnemite. The boy's sister needs his help, despite the boy not having a battle in his life. The boy sends two Pokémon - Plusle and Minun. The Plusle and Minun cheer Magnemite, sending an electric surge into the sky and back to power Magnemite up. Magnemite is stronger than before.
Ash and Brock attempt to persuade the boy's sister that they are not thieves, but with no success. The boy's sister states it is their stone, so Ash gives it back, but Team Rocket appears, demanding the stone. Team Rocket blasts off when Pikachu used Thunderbolt. The gang forgives the boy's sister for not trusting them. The gang went to the light house and the boy's sister explains that the stone is valuable because it is the source of light in the lighthouse.
Plusle and Minun touch the Light stone, making it glow for a period of time, since when Electric Pokémon can make it glow. The boy thinks Ash is the hero when he puts the jacket on, even mentioning to his sister Alyssa. The boy tells of the tale that a man got to the village with the Light stone, accompanied with an Electric Pokémon and when the village is in danger, the hero would return.
Thatcher, the boy, guide the gang through the village. He goes to get his grandpa and when Alyssa explains to grandpa what Thatcher thinks, even the old man is convinced. Thatcher tells Ash that he wants to battle someday, since Plusle and Minun help others out in need, so Ash will help him. Ash gives coordinates to Thatcher how to be a hero - he needs to understand his Pokémon, to smile (even in grim moments), to be quick and needs to build his own stamina!
The rest of the gang wonder when Ash's going to stop with hero routine, but Alyssa makes a flashback when she had to support Thatcher when he thought his Pokémon did not deserve him. Alyssa spots the fog again, so everybody need to go to the lighthouse. Alyssa's Magnemite powers the Stone up, but Ash and Thatcher notice a Zapdos machine in the sky - it's Team Rocket again. They cut the support poles, making the roof fall off the lighthouse. Magnemite uses Thunderbolt, but the attack is deflected.
Team Rocket steals the Light Stone and Magnemite. Pikachu uses Thunderbolt, but with no effect. Thatcher needs to battle with Team Rocket, while Pikachu has been stolen. Team Rocket throws Magnemite away, since they have Pikachu already. They go away, with Thatcher blaming himself for Pikachu getting stolen. Ash tells him he is not a hero, but he will rescue Pikachu and the stone. Ash yells that Pikachu should use Thunderbolt on the Light Stone, despite Thatcher's skeptics. Team Rocket has come down, but Pikachu uses Thunderbolt to light the stone. Ash tells Thatcher he should just trust Plusle and Minun for battling.
Team Rocket east, but the gang appears. Team Rocket goes up. Plusle and Minun use Helping Hand to power Pikachu up. Pikachu uses Thunder, negating the electric resistances and freeing themselves. Plusle and Minun use Helping Hand on one another. They use Spark to blast Team Rocket away. Ash promises to battle Thatcher one day, with Thatcher calling him as "Master". They go off to Mauville City.

Come on, guys!" - Ash.
- Ash trips and falls into mud.
When James sent Cacnea to use Pin Missile, it was miscolored - green parts were colored in black.
