Bidding their old friends goodbye, our heroes again set their sights on Nimbasa City and Ash’s next Unova Gym Battle!
The episode is a continuation of the Club Battle Tournament in Nimbasa Town. The episode starts with Ash and his Palpitoad battling against Dino's Darumaka. Ash commands his Palpitoad to use Hydro Pump, defeating Darumaka and taking Ash into the finals.
Immediately afterwards is the battle between Luke and Iris. Luke looks over to find Bianca filming his Zorua when he had asked her to film his battle. He turn turns his attention back to the battle and sends out his Golett while Iris confidently sends Axew into battle. Iris commands Axew to use Scratch. However, Golett took no damage due to its Ghost type, making Normal-type attacks useless. Golett counterattacks by using Mega Punch, landing a direct hit. Axew then tries to attack with Dragon Rage, while Golett uses Double Team, causing Dragon Rage to miss its mark. Luke commands his Pokémon to use Gyro Ball while its two other copies do the same. Axew manages to keep an eye on the upcoming attacks until two of them spin in opposite directions, making Axew confused. The three attacks hit the Tusk Pokémon at the same time but Axew is still standing. Iris sees an opportunity to attack and commands Axew to use Dragon Rage again. Luke tells Golett to use Shadow Ball, as its copies disappear and it forms a dark, purple ball in its hands. Golett throws it towards Axew as the two attacks collide into each other and a giant explosion is created.
Luke tells his Golett to use Gyro Ball once more as Iris tells Axew to run from it. Golett continues to chase Axew for a while until Axew stumbles over, exhausted from running. As Golett closes in on Axew, Iris dramatically yells Axew's name. Golett is surprisingly thrown up into the air while Axew stands with a bright red aura around it. When Golett reaches the ground, Axew angrily attacks it continuously with punches and powerful kicks. One of Axew's kicks sends Golett into the air, Golett then smashes against the arena's border wall and faints. The judge announces Iris the winner and will be advancing to the final round against Ash. She rushes towards her Axew and congratulates him on learning Outrage as Axew begins to sleep.
Afterwards, everyone heads back to the Pokémon Center and Luke is shocked to discover all the footage Bianca shot was of his Zorua. Bianca shrugs off her actions and offers Zorua handmade accessories as gifts, and partial bribery to become her Trainer. Zorua refuses these gifts, and Luke reminds Bianca that he's not interested in trading away his star actress. Luke then remembers that he should interview Ash and Iris, the finalists, for his film. In the dining room, Cilan presents his friends and their Pokémon with their dinner which he was permitted to make in the Pokémon Center's kitchen to celebrate Ash and Iris's victories. During their meal, Burgundy approached Cilan and challenged him to a Connoisseur Showdown to evaluate his prowess as a connoisseur. He rejected the invitation at first, but then noticed Luke behind Burgundy filming their conversation. Cilan could not hold back putting on a performance for the camera, and immediately accepted Burgundy's challenge with confidence. The change in personality startled Burgundy, and Stephan appeared behind them and volunteered to be their referee. Meanwhile, Team Rocket is hiding out in one of the Ferris Wheel's carriages in Nimbasa City, reviewing their newest plan. Meowth mentions there is one thing left to be taken care of and he will take care of it.
The next day, the final battle between Iris and Ash commences, as does the Connoisseur Showdown between Burgundy and Cilan. Ash sends Pikachu into battle while Iris decides to use her Excadrill. Ash starts the battle with Pikachu using Thunderbolt, which naturally has no effect on a part Ground-type like Excadrill. Iris then tells Excadrill to use Drill Run. Ash cleverly commands Pikachu to use Quick Attack which helps it dodge the attack. However, Iris's Excadrill grabs Pikachu's tail between its claws and thrusts Pikachu across the arena, and then slams it using Metal Claw. However, Pikachu manages to flip around and get back on its feet. Cilan and Burgundy continue to comment about Ash's and Iris's battle as Luke and Bianca film.
Ash's Pikachu uses Iron Tail while Excadrill uses another Metal Claw. The two dive towards each other but Pikachu dodges the opposing Pokémon's attack and slams Excadrill to the ground. Iris follows up with Focus Blast while Pikachu charges up Electro Ball. The two attacks collide into an electric light explosion. Burgundy comments on the explosive power between Pikachu and Excadrill, and Cilan responds in agreement and confidence in the two Pokémon's power. Burgundy realizes Cilan's choice of words shows far more experience than her own, and Cilan politely offers to end the showdown, which Burgundy accepts and the two continue watching the battle in silence. Iris's Pokémon drills into the ground and attacks Pikachu. Ash suddenly tells Pikachu to keep spinning and it uses the momentum to land a powerful Iron Tail into Excadrill's face. Despite the powerful attack, Excadrill still stands. It uses Drill Run while Ash tells Pikachu to use another Iron Tail. However, right before Pikachu can execute its attack, the opposing Pokémon rams into Pikachu, making it fall to the ground. Pikachu still manages to stand as Excadrill digs into the ground but misses Pikachu when it rises up. Iris then commands it to use Focus Blast which lands directly into Pikachu, causing it to fly backward and smash against the wall, also making Pikachu faint. With that final attack, the judge proclaims Iris the winner of the Club Battle Tournament. The crowd cheers for Iris and she is gifted a display case of Wings. She stands in the center of the stadium with her two Pokémon, Axew and Excadrill. At the end of the episode, Ash, Iris, and Cilan bid farewell to their friends as they all go their separate ways.
