Professor Agasa takes Conan and the Junior Detective Boys (Detective Boys) on a summer trip to a beach in Shizuoka. Coincidentally, Ran and Sonoko are vacationing at the exact same beach.
While enjoying the water, the group meets a local lifeguard named Teiji Shimojo and his diving team friends. That evening, the group gathers at a hotel restaurant to eat dinner with the lifeguards. However, the team's head lifeguard, Giichi Aramaki, fails to show up. When they try to call his mobile phone, they hear nothing but the sound of the ocean waves.

The local police (led by Sango Yokomizo) are called in when Aramaki's corpse is eventually found tangled up in a fishing net. Conan must figure out how the killer manipulated the tides and timing to commit the murder. 🧠 Major Character Development
This case is highly regarded by fans due to the silent psychological battle and eventual breakthrough between Ai Haibara and Ran Mouri. Haibara's Distance:
Throughout the beach trip, Haibara noticeably avoids Ran. She compares herself to a "shark" coming from the dark, cold depths of the ocean (an allusion to her life in the Black Organization), while viewing Ran as a bright, pure "dolphin" loved by everyone. Ran's Famous Quote:
In the resolution of this case (which carries over into Episode 247), Ran famously scolds the murderer for trying to justify his crime by saying he acted with courage. She states:
"Courage is a word of justice. It means the quality of mind that enables one to face apprehension with confidence and resolution. It is not right to use it as an excuse to kill someone." The Breakthrough:
Ran's selfless nature and her lecture on true courage finally break through Haibara’s emotional walls, causing Haibara to formally introduce herself to Ran at the end of the case. 🔍 Anime vs. Manga Differences The Movie Scene:
In the manga, Haibara turns off a television playing the 1997 movie
. In the anime adaptation, this was replaced with a generic movie credit screen written in French against an ocean background (which many fans believe was a nod to the 1988 film The Big Blue Outfit Change:
The animators changed Haibara's clothing in the hotel room, putting her in shorts instead of the dress she wore in the manga panels. Detective Conan Rewatch: Episode 246-247 Memorable elements
Anime fans are currently experiencing a deep wave of nostalgia for early 2000s anime (the "Heisei era"). The updated visuals allow younger fans to enjoy the story without the jarring quality drop of old SD resolutions.
To understand why people are searching for an updated version, we need to look at the episode's place in the series.
This two-part story (Episodes 245 & 246) is a classic "locked-room" mystery on water. It follows teenage detective Heiji Hattori and Conan as they investigate a death aboard a luxury yacht. The twist? The primary suspects are the victim's own competitive brothers, each with airtight alibis.
The reason Detective Conan Episode 246 updated is trending is that the new visuals finally make the trick visible. In the original SD version, the key clue—a scratch on a metal pipe—was nearly invisible.
The Trick (Simplified):
The remaster includes a new CGI overlay during the explanation scene, showing the rope’s trajectory in neon blue. This "updated" infographic has become a clip that goes viral on TikTok and Twitter every few months.
To understand the update, we must first look at the original. Episode 246 is titled "The Mystery of the Trapped in the Net" (圏内の謎). It originally aired in 2001 during Season 9 of the series. This episode is part of a two-part story (Episodes 246-247) based on chapters from Gosho Aoyama’s manga (Volume 31, Files 1-3).
The recent "update" refers to the official digital remastering and high-definition (HD) conversion released by streaming platforms like Crunchyroll, Netflix (in select regions), and the official Detective Conan YouTube channel. This is not a full remake like Episode One: The Great Detective Turned Small, but rather a significant audio-visual polish.
Most Detective Conan episodes focus on the crime. Episode 246 focuses on the motives. The killer is a younger brother who felt overshadowed. The final scene, where Heiji talks about protecting what matters (glancing at Kazuha), is a rare moment of vulnerability. The "update" in audio quality makes Kazuha’s tearful gasp genuinely moving.
