Case Closed: Countdown to Heaven

The Junior Detective League, along with Conan, Ai, and Dr. Agasa, heads out on a camping trip. They notice Mount Fuji and the newly constructed Twin Towers in the distance. Later, Genta sees Ai talking to someone in the night, hinting at a developing secret.

Gin and Vodka sneak into Akemi Miyano's flat and listen to messages on the answering machine. They learn that Shiho Miyano will attend a private viewing of the Twin Towers in West Tama City. They plan to murder Shiho there.

The group visits the Twin Towers, described as ‘the closest thing to heaven.’ Augustine Odell, drunk, invites Madison over for the night in the tower, while a Porsche 356A car glimpse links to Gin. Later that night, Augustine Odell is brutally murdered.

A broken sake cup is found and Augustine's painting is missing, suggesting the murder may carry a message. Police note the cup could have fallen during the murder or been left deliberately as a clue. The Junior Detective League interrogates Theodore and Kisaragi; after questioning, the group disbands.

Vi is seen talking on the phone at Dr. Agasa's house, unaware that Black Organization members Gin and Vodka are listening on the other end. The scene heightens the sense that danger is closing in on the group.

The following day, the kids interrogate Yoshiaki Hara at his home and discover he is dead, a knife in his hand with a broken sake cup nearby. Police conclude a serial killer is at large and note that Hara's computer data has been erased, removing crucial clues.

Inspector Meguire pleads to postpone the Twin Towers grand opening, but Madison refuses and proceeds with plans. Security is compromised as guards are knocked out with sleeping gas and bombs are planted around the complex. The stage is set for a catastrophe that will draw many suspects together.

During the grand opening party, Madison hosts a 30-second guessing game and presents Kisaragi's painting with other staff assisting behind the scenes. As the curtain rises, Madison is found dead with a painting in the background and a message left by the killer. Haibara offers a hint that helps Conan push the investigation forward.

Before the killer is revealed, bombs detonate, setting the building ablaze. Serena, Conan, and Rachel evacuate in a glass elevator; Conan realizes Serena's new perm makes her look like Shiho from behind and distracts Gin from shooting her.

Conan re-enters the tower to confront the serial killer, Kisaragi. He exposes Kisaragi's method of murdering Madison by removing her pearl necklace and attaching an identical one to his painting with fishing line. A broken sake cup serves as another clue, and Conan discovers Madison's original necklace in Kisaragi's cane; he tranquilizes Kisaragi to prevent suicide.

With bridges blown and the bottom floors on fire, Conan powers a Ford Mustang to propel the kids and himself to safety. They reach the ground amid the inferno, narrowly escaping the collapsing structure.

After the chaos subsides, Gin and Vodka confirm that Shiho Miyano was not at the towers and decide to abandon their pursuit for now. The search for Shiho remains unresolved, leaving a lingering sense of danger.
