While touring Alamos Town, home of the Space-Time Tower, with the beautiful Alice, Ash and his friends discover that the town's special garden has been decimated.

Ash, Dawn and Brock continue to collect and train new Pokemon on their travels. Along the way they meet up with Pokemon fossils brought back to life and a mercenary Pokemon thief who can out-thieve even the Team Rocket. But if those challenges can't bring down our heroes, nothing can.

Ash and Brock are back for more adventure. Joining them is Dawn, a young girl who dreams of one day becoming a great Coordinator like her mother. Together the three will travel through the Sinnoh region, collect new Pokémon, face down Team Rocket, and continue with their training so they can be their best.

Dawn finds that collecting Pokémon is no easy task, and training them can be even harder. The work pays off as she, Ash and Brock make their way to Eterna City for Ash's next gym battle, then on to Hearthhome for the Sinnoh Double Battle Tournament. The biggest challenge of all might just be in getting there. Maybe a Pokémon with teleportation skills can give them a hand.

Join the Pokémon as they team up with their friends/trainers in more battles to decide who is the greatest Pokémon of all!
