In 1999, a mystical Arrow, which can manifest latent Stand abilities, travels throughout Morioh, Japan.

Production
Initial rumors in July 2016 of a movie adaptation of Stardust Crusaders being in production began to circulate only for no official confirmation to validate the authenticity of the claims. Eventually on September 28th 2016, at a panel to promote JoJo's Bizarre Adventure the film was revealed to the public, instead being an adaptation of Diamond is Unbreakable. producer Takashi Hirano explained that the staff decided to adapt the manga's Part 4 storyline since it features a Japanese protagonist in a Japanese setting. He then further clarified that the cosmopolitan nature of the manga offers a chance for Japanese cinema to expand across the world; including actors of a particular Part (such as English or Italian characters) to be played by their appropriate race.

In regards to the film's subtitle of "Chapter I", Hirano explained that due to the complexity in the plot and characters of Part 4 it would be impossible to adapt its entirety into a two-hour film. Hirano then said that if the film is a commercial success, he'd love to adapt the remainder of Part 4 through more films. Director Takashi Miike decided on the Spanish city of as the shooting location after looking through options worldwide. He acknowledged that the original manga's setting is loosely based on the real Japanese city of Sendai, but determined Sitges was the closest match to Morioh's fictional setting.
