Ash, Goh, and Chloe are in the bustling city of Vermilion, where they are excited to explore the local Pokémon Center. As they arrive, they notice a commotion outside. A group of trainers is gathered, discussing a recent string of thefts involving Pokémon. The trainers express their frustration and concern, as several of their Pokémon have gone missing.

Intrigued by the situation, Ash and Goh decide to investigate the thefts. They split up to gather information, with Ash heading towards the local marketplace while Goh and Chloe stay back to talk to the trainers. At the marketplace, Ash encounters a young girl named Marnie, who is distraught because her beloved Thievul has been stolen. Marnie explains that Thievul is not just a Pokémon to her; it's her partner and best friend. Ash empathizes with her and promises to help find Thievul.

Meanwhile, Goh and Chloe learn from the trainers that the thief is rumored to be a skilled Pokémon trainer known for using stealth and cunning tactics. They also discover that the thief has been targeting trainers with rare Pokémon. This information heightens their determination to catch the thief and recover the stolen Pokémon.

Back with Ash, he and Marnie decide to team up. They begin to search the area for clues, retracing Thievul's last known steps. As they investigate, they come across a series of footprints leading into a nearby alley. Ash and Marnie follow the trail, their hearts racing with hope. They find a hidden entrance to an underground hideout, where they suspect the thief might be keeping the stolen Pokémon.

As they enter the hideout, they are met with a dimly lit room filled with various stolen Pokémon. Ash and Marnie are shocked to see Thievul among them, but before they can act, the thief appears.

Ash recalls Pikachu and sends out his Galarian Farfetch'd, who uses its agility to dodge attacks and land critical hits on Weezing.

As the battle rages on, Kaito becomes increasingly frustrated. He decides to use Thievul to turn the tide, but Marnie intervenes, pleading with Kaito to return Thievul to her.

In a final showdown, Ash and Marnie combine their efforts, with Farfetch'd and Thievul working together to defeat Kaito's remaining Pokémon. The battle culminates in a powerful combination attack that knocks out Kaito's last Pokémon, leading to his defeat. Kaito, realizing the error of his ways, surrenders and returns all the stolen Pokémon, including Thievul, to their rightful owners.
