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.
