The story begins when ace detective Harry Goodman goes mysteriously missing, prompting his 21-year-old son Tim to find out what happened. Aiding in the investigation is Harry's former Pokémon partner, Detective Pikachu: a hilariously wise-cracking, adorable super-sleuth who is a puzzlement even to himself. 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.
The Japanese release of this film is dedicated in memory to fellow Pokemon voice actor Unshô Ishizuka who died a year before this movie. See more »
Early in the film, Tim makes mention of Aipoms. In another scene, Pikachu says something about being attacked by Greninjas. The screenwriters of the film apparently didn't know that the plural form of a Pokemon is the same as the singular form; you don't need to put an "s" on the end of the species name to make it plural.
