Yamato's eye injury isn't just a plot device, it's the emotional hinge the whole movie turns on, forcing you to question what he's willing to hide and why. The supporting cast finally gets real weight here, their relationships grinding against each other in ways that land harder than Conan's usual deductions. This is a Detective Conan film that remembers the people matter more than the puzzle.
A researcher lies bleeding in the Yatsugatake Mountains, and Detective Kansuke Yamato arrives on scene with his partner Yui Uehara. But something's wrong. A sudden pain in Kansuke's eye, an old injury resurging, threatens to derail the investigation. Before they can make sense of it, another body surfaces: Kogoro's former colleague, murdered under circumstances that point back to an incident buried in Kansuke's past. Conan knows better than to ignore this kind of timing. He pulls in Amuro and Kazami, assembling a team to chase down a mystery that keeps doubling back on itself. Someone's orchestrating these deaths. Someone with a grudge tied to Kansuke's history. As the pieces come together, the real question isn't just who killed these people, but why they're being killed now, and what Kansuke's been hiding all these years. The clock's ticking, and the mountains hold secrets that someone would kill to keep buried.
