Ash and his friends arrive in Shalour City, where they discover that the next gym is located. However, as they attempt to seek out the gym, Ash finds out that he must complete a challenge before he is allowed to challenge the gym leader.

The challenge is a Pokémon race called the Rhyhorn race, where trainers must navigate through a challenging obstacle course atop Rhyhorns without falling off or getting knocked over. If they succeed, they are given the opportunity to challenge the Shalour City Gym Leader.

Ash and his friends decide to take on the challenge, and while they race, they encounter Team Rocket, who tries to sabotage their progress. With quick thinking and determination, Ash and his friends manage to complete the race and earn the right to challenge the Shalour City Gym Leader.

However, when they arrive at the gym, they find out that the leader is none other than Korrina, the person who gave Ash the Lucario he currently has on his team. Korrina is excited to see Ash and his friends and agrees to battle him.

The battle between Ash and Korrina proves to be intense, with both trainers giving it their all. Korrina holds her own and proves to be a powerful trainer, but Ash manages to come out on top, earning him the Rumble Badge and bringing him one step closer to becoming a Pokémon Master.

The episode ends with Ash and his friends bidding Korrina farewell as they continue their journey towards their next destination, eager to see what challenges and adventures await them in the next episode.
