| Makoto meets Sonoko's parents and isn't satisfactory to Tomoko, Sonoko's mom, because she wants a well read man to succeed the family. When Sonoko gets all hyperexcited at Kaito Kid's next notice, Makoto goes to her uncle Jirokichi to safeguard the gem Kid is after to prove his worth to Sonoko. When Jirokichi hears Makoto has NEVER lost a fight, he uses him to guard the Green Emperor gem. Kid accepts the challenge, and gets close to the gem by posing as Sonoko. Makoto immediately realizes Sonoko is really Kid who tries to escape, but Makoto follows undeterred and Kid admits defeat. Makoto reveals he knew Kid was in disguise because of the finger length difference from the real Sonoko.
When Azusa tries to find the owner of the boy Calico cat Taii, three people claim ownership: an elderly woman, a freeter, and a company president. The woman learns her cat is a girl from Conan; the freeter is a con-man because a calico male is a 1/1000 find valued between 1 and 20 million Yen; the company president, Teishi Masuko, is the real owner as the cat remembered him as he used the moving service from the refrigerated truck where the kids first found Taii. When the kids go visit Mr. Masuko, he had received a head injury from an assault. Takagi and Sato investigate, and Takagi let slip the two slept together. The Detective boy later meet Makabe, a boy with a new game they all like, so he invites them over. Conan finds a dead man next door to Makabe, and Takagi and Sato are called in. Sato tells Takagi that she lost something because of him, and he says he will take responsibility (him believing it is because they "slept together" she is pregnant). Meanwhile, Yumi and Naeko eavesdrop on the conversation between the two, both believing Miwako to be having Takagi's child- which Yumi spreads over HQ infuriating all the men. It turns out Sato lost a pin she normally wears when she and Takagi were after a suspect, only to find it in his pants pocket- meaning she isn't pregnant.

| Conan, Ran, and Sonoko head to a cabin in the woods with Masumi to meet some of her brother's old friends to solve a mystery. Along the way, they saw a woman dressed in all red hiding but vanished when seen. When they arrive they meet Tamami Minegishi, Sumika Kawana, Masaie Hakuya, and Jinsuke Ninda. Ran mentions the woman in all red from earlier, and everyone panics believing her the killer, the Red Woman- from her blood soaked coat- who killed their friend Satoko in the nearby bog 15 years earlier; since then, strange things have happened at the villa, so Masumi was asked by her brother to investigate. Masaie is later found murdered in the bath tub, and Yui Uehara responds to the scene and concludes Masaie was bludgeoned and drowned. Everyone says it was the Red Woman, but Uehara assures them it can't be since her death was confirmed 15 years ago along with Satoko's in the bog, her name was Komayo Takeno. The murder weapon is a dumbbell, and Masumi noticed salt in the tub, so Conan and Masumi confirm their deductions when a blackout occurs and Sumika is attacked by the 'Red Woman', leaving both detectives confused. Uehara learns Masumi spent 3 years in the US; she returned to Japan and in her head says "to meet the wizard once more" while looking at Conan. Inspectors Kansuke Yamato and Taka'aki Morofushi (Komei) look into the original Red Woman case by talking to the original officer on the case.
Reviewing both Satoko's and the Red Woman's deaths, Satoko was found with a red coat of the 'Red Woman', while she wore beige earlier that day. Yamato calls to warn Uehara of a danger in the woods, but the call dies from a storm. Conan and Masumi deductions prove Sumika was the one who killed Masaie and hid him in the tub. By using a bat and a fan to create the sounds of a vacuum to sound like Masaie was upstairs, he was already dead. Conan also shows that tomatoes don't float unless salt is mixed with the water, so she salted the water to create an alibi. Masumi also points out that she was the woman in red they saw on the way to the cabin as she handed Masumi the photos from earlier to investigate, without hesitation while the others thought she was a boy at first. She killed Masaie as he had Satoko play the Red Woman for a prank, and she fell into the bog and died. The woman who attacked Sumika appears(Shinobu Kagawa, the mistress of the man killed by the Red Woman, attacked Sumika dressed as the Red Woman), but Yamato and Morofushi arrive and take her away. Conan later finds Masumi's phone and a young girl with Shuichi eyes is with her in the shot. Following their return to Beika, Masumi explains to Ran and Sonoko that a good friend of her dad's is paying for her stay at her hotel. Conan silently questions the photo of the little girl with Masumi since she said her only other siblings are her deceased and second brothers. They visit her hotel and run into a romance novelist, Hiura, writing his latest book, and his assistant, Chiaki Minazuki, is murdered. Immediately, Conan and Masumi see its the novelist and prove he used his suitcase to stuff her in after strangling her. He killed her because he thought she was trying to extort money and fame from him. She was the real original author when she was much younger and sent a coded message in the title to tell him that she loved him with a play on words with the book title. After Hiura is arrested, Conan's bug on Masumi is destroyed and the little girl from Masumi's photo comments on Conan still having a long way before earning her trust. Masumi is then told to say, should she be asked, that the little girl is her little sister from "outside the domain".
