The story starts with Togawa sisters, Satomi and Miki, receiving a golden statue. They lost their parents at an early age, never knowing what actually happened to them. One day, a letter came from a wealthy person living on an island somewhere in the western Japan Sea. Upon receiving this letter, they realized the golden statue belongs to the place from which the letter was sent.

As Conan and the others opened the Togawa sisters' request, they decided to help uncover the mystery behind their lineage and golden statue and set off on a trip to the solitary island in question where ships travel to only twice a week. As they arrive on the island of strange shape, the notice the residents of an island village appear a bit weird, and there seem to be history behind the wealthy island family. And to top it all, the murder in front of the wealthy looking western-style estate occurred just in front on them and the murderer ran away from the scene of the crime. It's Conan's task to solve all the mysteries and catch the killer, for by his own words, the truth is always only one.
