Meitantei Conan: Highway no Datenshi Season 1 Recap

Spoiler Alert: This recap contains detailed plot summaries and may reveal key story events.

TL;DR

Meitantei Conan: Highway no Datenshi is the 29th Detective Conan feature film, bringing the spotlight to two fan-favorite fallen heroes from the Police Academy arc — Jinpei Matsuda and Chihaya Hagiwara. Set against high-speed highway action and the franchise’s signature locked-room mystery tension, this Spring 2026 entry digs into the emotional backstory of characters the series has mourned for years. If you’re a Conan faithful who’s been waiting for the Wild Police Story threads to hit the big screen, this is the payoff.

Season Summary

As the 29th theatrical installment in the long-running Detective Conan franchise, Highway no Datenshi — “The Fallen Angel of the Highway” — is a feature film rather than a traditional TV season. Below, we break down this Meitantei Conan: Highway no Datenshi season 1 recap by the movie’s major narrative movements.

Act I: A Case on the Expressway (Opening)

The film opens with Conan Edogawa and the Detective Boys — including the ever-hungry Genta Kojima — on what should be a routine outing with Professor Hiroshi Agasa. A seemingly ordinary highway trip takes a deadly turn when a catastrophic incident unfolds on a major expressway, trapping civilians and pulling Conan into an investigation that quickly spirals beyond a simple accident.

Ai Haibara’s sharp instincts pick up on early anomalies that others dismiss. The setup establishes the film’s dual identity: a present-day highway thriller and a deeply personal story about loss, sacrifice, and the officers who never made it home.

Act II: Ghosts of the Police Academy — Matsuda and Hagiwara’s Story (Core Investigation)

The investigation draws Conan into the orbit of Chihaya Hagiwara, a key figure connected to the late Kenji Hagiwara — the bomb disposal expert whose death remains one of the franchise’s most gut-wrenching moments. Chihaya’s involvement in the case forces the narrative to confront the legacy of the Police Academy cohort, particularly the bond between Kenji Hagiwara and Jinpei Matsuda.

Through flashbacks and case evidence, the film unpacks the emotional weight these two men carried. Matsuda, the hot-headed bomb tech who died defusing a device meant to kill hundreds, and Hagiwara, whose own death preceded his friend’s — their intertwined fates become central to understanding the present-day threat. The “fallen angel” of the title takes on layered meaning as the highway case reveals connections to unresolved business from their time on the force.

Chihaya’s perspective adds a civilian dimension rarely seen in Conan films. She isn’t a detective or an officer — she’s someone left behind by the violence that defines this world, and her presence challenges Conan to consider what justice looks like for those who grieve.

Act III: The Highway Trap (Escalation)

The middle act ratchets up the tension as the expressway becomes a battleground. The culprit’s plan is revealed to be far more elaborate than an isolated incident — it’s a calculated operation exploiting the highway infrastructure itself. Vehicles, speed, and confined lanes become the weapons.

Conan’s deductive brilliance goes into overdrive as he pieces together the bomber’s methodology, drawing direct parallels to techniques Matsuda and Hagiwara would have recognized. The film stages several set-piece sequences on the highway that rank among the franchise’s most technically ambitious action scenes, blending vehicle chases with the ticking-clock bomb scenarios the series does best.

Major Spoiler — The Culprit's Connection

The antagonist's motivation ties directly back to the same incident that claimed the lives of the Police Academy officers, reframing a tragedy the audience thought they understood. It's not revenge in the conventional Conan sense — it's someone who was broken by the same system that created the heroes.

Act IV: Defusing the Fallen Angel (Climax & Resolution)

The climax brings Conan face-to-face with a threat that demands both intellectual precision and raw courage. In classic Conan movie fashion, the final sequence is a race against time where one wrong deduction means mass casualties.

The emotional payoff centers on Chihaya, who must confront her brother’s legacy head-on rather than living in its shadow. Matsuda and Hagiwara’s story reaches its conclusion — not through new revelations about their deaths, but through the living carrying their ideals forward.

The resolution ties the highway case shut while leaving the audience with the bittersweet warmth that defines the best Conan films: the mystery is solved, the day is saved, but the people we lost aren’t coming back. What endures is the mark they left on those still standing.

Highlights & Must-See Moments

• The Expressway Set-Piece — A multi-vehicle, high-speed sequence that pushes TMS Entertainment’s animation to its limit, rivaling the best action scenes in the franchise’s 29-film history.
• Matsuda and Hagiwara Flashback — A quiet, devastatingly human scene between two friends who don’t know they’re running out of time. The emotional core of the entire film.
• Chihaya’s Confrontation — A standout dramatic beat where grief and resolve collide, giving the film a civilian heart that grounds all the spectacle.
• Conan’s Highway Deduction Scene — Shinichi’s genius applied at 120 km/h. The “aha” moment is both visually inventive and narratively satisfying.
• Haibara’s Quiet Observation — Ai gets a small but perfectly placed moment that reminds the audience why she’s the franchise’s best supporting character.

Our Take

Highway no Datenshi represents the franchise leaning into what made the Wild Police Story spinoff so beloved — the humanity behind the badge. By centering Chihaya Hagiwara and the ghosts of Matsuda and Kenji Hagiwara, the film earns its emotional moments rather than relying solely on spectacle. It’s a welcome shift after several Conan films that prioritized scale over story.

The highway setting is inspired. Compared to the skyscrapers and stadiums of previous entries, the confined, linear geometry of an expressway creates a uniquely claustrophobic tension. If Zero the Enforcer was the franchise’s political thriller and The Scarlet Bullet was its tech showcase, this is its character study — and it’s stronger for it. The Meitantei Conan: Highway no Datenshi season 1 summary is ultimately a story about inheritance: what the dead leave behind, and what the living choose to do with it.

Rating: 8.2 / 10 — A heartfelt, action-packed entry that honors the franchise’s most tragic characters while delivering the mystery thrills Conan fans expect.
