👀 SPOILER-FREE SUMMARY

A classic Conan setup episode that nails the formula: take the Detective Boys somewhere fun, then let the mystery creep in. Professor Agasa brings the kids to a hot spring resort, where the relaxed vacation atmosphere collides with a film crew shooting a hitman drama on location. The episode thrives on contrast—lighthearted banter and comedic antics from Conan, Haibara, and the rest of the group play against an increasingly tense undercurrent as the resort's guests and crew reveal their quirks and conflicts. This is Part 1 of a two-part locked-room mystery, so expect deliberate scene-setting and character introductions rather than rapid-fire deductions. The hot spring locale gives the episode a distinct atmospheric quality, swapping Conan's usual urban playground for something moodier and more confined. Patience here pays off in the second half.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Hot Spring Arrival

Conan and the Detective Boys arrive at a hot spring resort and cross paths with popular actress Mishio Natori during an active film shoot — setting the stage for what should be a relaxing trip but clearly won't be.

Tetsuyama Found Dead

Veteran actor Ganji Tetsuyama is discovered lifeless in the sauna, slumped over as though he suffered an accidental fall. The initial assumption is a tragic accident caused by the extreme heat.

Conan Spots the Cracks

Conan's sharp eye catches inconsistencies at the scene that don't line up with a simple accident — small details others overlook that immediately shift his suspicion toward murder.

The Dressing Room Clues

Police uncover a strange collection of evidence in the dressing room: a plastic tea bottle filled with water, match cinders floating on the surface, and Tetsuyama's distinctive silver-gemmed ring. Each item raises more questions than it answers.

The Locked Sauna Problem

Conan begins piecing the clues together, zeroing in on the locked sauna as the central puzzle. How did the killer commit murder inside a sealed room — and which of the suspects had the means to pull it off?

📍 ARC CONTEXT

This episode pivots away from the urban setting of the preceding 'The Alibi of the Fall' case, relocating Conan and the Detective Boys to an atmospheric hot spring resort for a fresh investigative backdrop. It serves as the first half of a self-contained two-part locked-room mystery, with all the groundwork laid here paying off directly in Episode 598, 'The Scenario of the Steaming Locked Room (Part 2).' As a canon episode deep into Conan's long run, it delivers a standalone case that rewards fans of the show's classic detective format without requiring broader plot knowledge.
