Case Closed (Detective Conan)

Sera heads to the rental villa to meet a client with Conan, Ran, and Sonoko. On their way, Ran and Sonoko spot a woman dressed in red from head to toe. At the rental villa, Tamami, Sumika, Ninda, and Hakuya, members of a former high school outdoor club, had gathered. 15 years prior, a wife stabbed her husband to death at a nearby villa.

Hakuya's body is discovered, and the Nagano police led by Uehara Yoshie begin their investigation. Uehara believes the culprit struck Hakuya on the back of the head with a blunt object and knocked him unconscious before drowning him in the bathtub.

Sumika is attacked by someone resembling the Red Woman, but the cut is shallow, and Uehara treats her with antiseptic. Uehara explains there was no mistake in the DNA test of the Red Woman. However, Uehera adds since over ten years ago around this time of year, rental villas in the area are robbed.

Comedian DoDonPa Rokusuke turns himself in at a police box for the murder of his talent agency's president Tendo Hideki. True to his testimony, Tendo is discovered at the agency dead from a blow to the head, and DoDonPa claims he struck the president with the metal bat found beside the body.

Conan feels something is wrong with DoDonPa's all too convenient alibi and begins to strongly suspect him. After taking on the guilt for a murder he didn't commit, DoDonPa becomes the man of the hour for trying to protect the reputation of his benefactor Tendo.

Conan, Ran, and Sonoko visit the hotel room where Sera is living. In the hallway on the 30th floor of Sera's hotel, editors A, B, and C wait for author Hiura Keigo to finish his manuscripts. Later, Hiura's assistant Minazuki Chiori is found murdered in the room directly below Hiura's.

Author Keigo Hiura's assistant Chiaki Minazuki is found strangled to death in a hotel. Hiura has a perfect alibi, but Conan and Sera are certain he committed the crime. They ask about the condition of Minazuki's room and get closer to the truth. A 20 year old postcard is discovered inside Minazuki's suitcase. It is addressed to Hiura, and the sender is not Minazuki but Jun Ota, which is also ...

Conan, Kogoro, and Ran arrive in Ishikawa Prefecture's Kanazawa and are met by tourism agency employees Yuzo Tanimoto and Moeko Miyazawa and event company president Yuya Tadokoro and his employees Osamu Kuranishi and Harumi Akiyama.

On a rainy day, Conan bumps into a suspicious man being purused by police. The man is a drug dealer, and he drops his notebook as he flees. The notebook contains a code written using subway station and line numbers, but some of the code washed away in the rain.

When Heiji arrives at Nihonbashi, the scene of the drug deal, he finds three people wearing or holding white roses. Heiji trasmits images of the three people to Conan using his cell phone.

Conan, Genta, and Mitsuhiko enter the Teimuzu River Kite Flying Event. Renno and Yatsukoshi form the opposing team. Yatsukoshi holds the kite string while Renno holds their kite and speaks on the phone with his wife Takami.

Renno is led between two posts without a rope barrier and falls into the river. Yatsukoshi, who had feelings for Renno's mistress, Kakura, whose younger sister had her emotions toyed with, and Takami, whose husband cheated on her, all had motives.

Conan, Agasa, and the kids visit a boarding house where they are greeted by Ryoko, Aya, and Juri, the three sisters who manage the building. Conan happens upon Aya and Juri's boyfriend Masahiko arguing. Aya is strongly opposed to Juri's relationship with Masahiko, who is known for being a bad boy.

Conan and his friends search for Ai, who disappeared on her way home from shopping. She is bound and imprisoned by a robber inside the home of her recent acquaintance Higaki Mitsuru along with Mitsuru herself.

While Conan and his friends are on their way home from school, a man being chased by the police grabs Ayumi and uses her as a shield. Later, the man passes out from an injury on the back of his head. Emergency medical doctor Kido and nurse Natsumi treat the man, but he remains unconscious and in serious condition.

A visitor named Reina is killed at Haido Central Hospital. The cause of death is asphyxiation caused by cyanide. Inspector Megure suspects hospital patient Juri and visitors Katsuki and Tokie, who were drinking tea with the victim.

The police fail to find the container used to hold the poison that killed Reina in the hospital room, and Megure believes it's likely the culprit took it outside to dispose of it.

Conan and Ran go to the Beika Aquarium where Ran and Shinichi once went on a date. During their date, a man was stabbed to death. The knife used in the stabbing was modified to prevent the victim's blood from getting on the culprit.

Conan and Kogoro are taken to a warehouse by the gang of thieves to wait for their boss Mr. Head. Suddenly Head's metallic altered voice comes over the speakers.
