Meitantei Conan Movie 28: Sekigan no Flashback

Ten months ago, detective Kansuke Yamato suffered the injury that left one eye scarred during an incident in the snowy Yatsugatake Mountains. When a researcher is attacked in the same region and Kansuke's old wound begins reacting painfully, the Nagano police realize that whatever happened back then may not be finished.

In Tokyo, Kogoro Mori hears from a former colleague who has been looking into Kansuke's past case, only for the man to be murdered before he can reveal what he found. Conan joins the investigation with Amuro and Kazami as police, public security, and repeated assassination attempts converge. The fading image locked in Kansuke's memory may be the key to a far larger crime.
