Finding that they are uniquely equipped to communicate with one another, Tim and Pikachu join forces on a thrilling adventure to unravel the tangled mystery. Chasing clues together through the neon-lit streets of Ryme City–a sprawling, modern metropolis where humans and Pokémon live side by side in a hyper-realistic live-action world–they encounter a diverse cast of Pokémon characters and uncover a shocking plot that could destroy this peaceful co-existence and threaten the whole Pokémon universe.
