Conan, Ran, Sonoko and the Detective Boys are invited to an island for free diving lessons, but bad weather prevents them from doing so. While walking around the island, they stumble upon a shooting of a promotional video by washed up actor Yuya Miyasaka. While they watch, they see that Miyasaka physically harrases many of the crew members. It starts to rain soon after and every one comes back inside, but Miyasaka is found murdered later on.
By process of elimination, the main suspects are fellow actress Saeko Akimoto, assistant director Eiji Yamamoto, stunt double Mitsuo Okita and cameraman Shingo Takayama.
Part 2
While trying to figure out who murdered washed up actor Yuya Miyasaka, cameraman Shingo Takayama is found dead as well due to falling off a cliff.
Conan figures out who the real murderer is and uses Sonoko to reveal that person to be none other than make-up artist Miki Kitagawa. Conan reveals that the previous murder was a fake perpetrated by Miyasaka, Takayama and Kitagawa. However when Kitagawa came back for Miyasaka, she killed him for real and then proceeded to kill Takayama by pushing him off the cliff. Kitagawa confesses to her crime and reveals that she was an aspiring actress in a show starring Miyasaka and wanted to show her grandmother the performance, but an incident caused by Miyasaka and Takayama cancelled the show and the episode was never broadcast. However, Saeko Akimoto yells at her and says she should have tried harder to make it as an actress and that such a reason was not an excuse for murder. Kitagawa breaks down after hearing her say that.
