The synopsis for 'Detective Pikachu' is as follows:

The story begins when ace private eye 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 movie also stars Justice Smith ('Jurassic World: Fallen Kingdom') as Tim; Kathryn Newton ('Lady Bird,' TV’s 'Big Little Lies') as Lucy, a junior reporter; and Oscar nominee Ken Watanabe ('Godzilla,' 'The Last Samurai') as Lt. Yoshida.

'Detective Pikachu' hits Irish cinemas on May 10th.
