On their way to Vertress City, site of the Unova League, our heroes encounter a rockslide in their path. Ash and Iris try to climb over it, and it gives way under their feet! But a young man with an Eevee comes to the rescue, and his Espeon uses Psychic to float Ash and Iris out of danger.
Their rescuer’s name is Virgil, and he—along with his older brother, Davy, and their father, Jeff—are part of the Pokémon Rescue Squad, dedicated to helping others in need. The squad consists of several teams, and Virgil’s team is called Team Eevee because it includes Eevee and all seven of its evolutions!
Soon, the squad receives a distress call from a nearby dam. Davy flies there to investigate and discovers that the entire lake and the dam’s control room have been frozen, knocking out the power and trapping a worker in the elevator. He evacuates the other workers, but a wild Cryogonal’s attack traps him inside the control room with the door frozen shut!
That means it’s Virgil’s turn to launch a rescue. Our heroes decide rescuing people with the help of Pokémon sounds like a great thing, so they come along to help! Virgil’s task is to recharge the emergency batteries to get the power back up and running. Iris and Cilan distract the five angry Cryogonal who are responsible for the crisis, and Ash and Virgil find the batteries and recharge them with the help of Jolteon and Pikachu.
Once power is restored, Davy goes to investigate the strange noises coming from the control room’s basement. There he finds the cause of the incident: a smaller Cryogonal trapped behind some pipes! He frees it with his Darmanitan’s help, and then discovers that Virgil’s Eevee has made a tunnel to rescue him using Dig.
Our heroes, Virgil, and Davy are soon reunited, and the little Cryogonal returns to its friends, who happily float away. The dam is thawed, the workers are safe, and thanks to Eevee’s heroic actions, it’s promoted as a full member of Team Eevee!
Before saying good-bye, Virgil reveals that he and Eevee won all eight Unova Gym badges on their journey together, and they’re planning to enter the Unova League too! Ash looks forward to an exciting new rivalry as our heroes resume their trek to Vertress City.
