Two years after Tim Goodman and Detective Pikachu solved the case behind the R incidents, and in the midst of their search for Tim's missing father, Harry, they are invited to be awarded medals for their continued detective work by Ryme City's mayor, Martin Myers, who hopes to initiate the inaugural Pokémon Friendship Week to redefine the harmony and coexistence between humans and Pokémon, following a recent rise in Pokémon-related incidents. However, a frenzied Corviknight interrupts the ceremony. After the two briefly help a wild Pidove knocked out from the chaos, they are called by Inspector Holiday to investigate theft of a priceless jewel at an estate owned by jeweler Sanjeev Denis.
At the Denis estate, the Ryme City police accuse Sanjeev's trusted friend and butler Brandon Barnes as a suspect. Believing Barnes has an alibi, Tim and Pikachu investigate, and with some help from Saujeev's Growlithe, Tim exposes the recent hire, Larry Turner, as the culprit, proven by a note written by him that reveals his plan to frame Barnes, hiding the stolen jewel in the belly of his Pokémon, a Cramorant. However, upon Pikachu noticing a strange device on Cramorant's back, it swallows the jewel and flies away, with Turner denying any further involvement.
After Tim invites his classmate Rachel for dinner with his visiting mother Irene and sister Sophia, Pikachu suddenly faints, recounting a conversation between Harry and Irene, the former deciding to file for divorce before leaving. Once Pikachu awakens, he and Tim are visited by Mewtwo, who reveals that the recent uptick of Pokémon incidents is not caused by R, but from something else, as well as preparing to disclose intel on Harry. Before explaining further, Mewtwo is attacked by a swarm of Beedrill, wearing the same mysterious devices.
The next day, Tim and Pikachu join Rachel to meet her professor, Trevor Gordon, at some mysterious ruins south from Ryme City, hoping to gain more information on the Aurora Drop. After discovering that Gordon had entered the ruins two days prior and hasn't returned since, the three investigate the temple's puzzles and solve the mysterious riddles. Along the way, they sneak past a Galarian Darmanitan protecting the area, soon finding Gordon trapped inside a mysterious room from a cave-in. Pikachu enters the room alone to help him and decides to befriend Darmanitan and use its strength to break through the debris.
With Gordon free, he decides to stay longer, resolved into his research, not before explaining to Tim the ruins' significance into strengthening the bonds of humans and Pokémon, but reveals that the Aurora Drop itself may be a Pokémon that hailed from space.
