👀 SPOILER-FREE SUMMARY

A filler two-parter kicks off with Conan, Ran, and Kogoro trading their usual Tokyo stomping grounds for the historic streets of Nagasaki. This is a change-of-scenery episode through and through — expect a slower, more atmospheric pace as the show leans into sightseeing and historical flavor before the mystery machinery starts turning. The Bakumatsu-era backdrop gives the episode a period-drama texture that's unusual for the series, weaving cultural heritage into the investigative setup. A cast connected to a historical drama production introduces fresh faces and fresh motives. If you enjoy Detective Conan at its most travelogue-like, savoring location and mood before the deductions drop, this opener delivers exactly that. The real payoff is clearly being saved for part two.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Crashing the Set

Ran, Conan, and Kogoro wander into an active Bakumatsu-era drama shoot in Nagasaki, bringing production to a halt. The crew quickly ropes Kogoro in to help solve their real-world problem — a vanished scriptwriter who left the story without an ending.

Clues in the Room

Investigating the missing scriptwriter's quarters, the group discovers newspaper clippings detailing a string of recent art thefts. The connection between the disappearance and the crimes starts to take shape, with Conan already piecing things together.

The Scriptwriter Slips Away

They briefly catch sight of the elusive scriptwriter lurking nearby, but he bolts before anyone can confront him. His deliberate evasion makes it clear he's hiding something far bigger than writer's block.

Ran and Conan Go On-Camera

After a mysterious email delivers the next script segment, the short-handed crew drafts Ran and Conan as extras in the Bakumatsu drama. It's a lighthearted beat that puts both of them directly inside the unfolding production — and closer to danger.

Attack on Set

The prop technician is suddenly assaulted during filming and, before losing consciousness, points the finger directly at Ran. The accusation drops a genuine whodunit into the middle of the fictional one, turning the drama set into a real crime scene.

📍 ARC CONTEXT

This standalone filler episode follows 'The Sandy Beach with No Footprints' and marks the first half of a two-part Nagasaki-set mystery with no connection to the series' overarching plot. It functions as setup, establishing the location, guest characters, and central intrigue that will be resolved in the subsequent episode, 'Nagasaki Mystery Theater (Present-Day Part).' Safe to skip for viewers tracking only canon storylines, but worth a watch for fans who enjoy the show's destination-driven cases.
