Heiji is invited to Yadori Village along with a historian, archaeologist, reporter, and a writer along with Conan, Ran, and Kazuha. Following a group dinner, a mysterious sound is heard and a fire is started outside. A mythical beast, known as a Nue is thought to be seen outside.

As the Nue appears again, the archaeologist has been poisoned, but everyone was visible while it happened. Conan and Heiji quickly move towards finding the culprit before another murder occurs.
