Deciding to go bowling after they are rained out for tennis, Ran, Sonoko, Masumi and Conan are met by Makoto, who engages Sera in a fight after mistaking her for a boy interested in Sonoko. After this is straightened out, we learn that he was attacked by teacher Masahiro Tanba, who was drunk. His coworker Sunami Masaki took him to the car to calm down. Makoto soon leaves to nap in the car, not finding bowling to be his strong suit.

Conan and Sera are going to clear Makoto as the suspect and find out the true murderer.

Sonoko has decided to introduce Makoto to her parents. Her father approves of Makoto but her mother doesn't. Makoto is going to prove himself by protecting the jewel which is the target of Kaitou Kid.

Kaitou Kid appears but he failed and gave the jewel back to Makoto as Makoto desperation to protect the jewel has led Kaitou Kid to surrender (although the jewel is not the one Kaitou Kid wants).

A man was found dead in an apartment.

Conan, Detective Takagi and Detective Sato are solving the mystery of the murder and tries to deduce who is murderer.

When Koutarou jumped into the ocean he suddenly was unable to swim and began drowning, eventually passing away at the hospital.

Three different people have come forward claiming Taii belongs to them. Now it's up to the group to determine who is telling the truth.

After unlocking the door, Conan runs into the bedroom to find Teishi barely breathing after apparently falling off a chair and hitting his head while fixing a light, but something doesn't seem quite right.

Ran visits her former school friend who now lives in a shared apartment house that goes by a bunch of scheduled rules. When Kogoro and Conan arrive to pick her up, one of the housemates is found dead on her bed, and suspicion is placed on the sole male housemate who had argued with her earlier.

Conan, Ran, Sonoko and Masumi are walking through the woods to a villa where Masumi’s brother was called to investigate the mysterious Red Woman, a person who is reputed to be haunting the area. They meet with a group of friends, Tamami Minegishi, Sumika Kawana, Masaie Hakuya, and Jinsuke Ninda who are there at to the villa to pay respects to their friend Satoko. It is believed that Satoko was murdered by the Red Woman after her corpse was pulled from the nearby swamp.

The investigation of Hakuya’s murder is led by Yui Uehara, Taka'aki Morofushi, and Kansuke Yamato of the Nagano Prefectural Police Department. Hakuya bashed the back of his head, fell in the tub after losing consciousness and drowned. The discoloration of the bath water is due to the bath salts. Alibis and suspect whereabouts are taken; Tamami was preparing dinner, Sumika was vacuuming rooms and Jinsuke went shopping.

Although Sumika’s attack is looked at, Conan and Masumi are not deterred from their conclusion and proceed with the investigation. They reveal that Sumika killed Hakuya. The pair reveal that Sumika bludgeoned Hakuya with the dumbbell and submerged his body in the bath water, killing him. She covered his corpse with tomatoes that sank to the bottom, then used her fan and a bat to simulate the sounds of a vacuum cleaner.
