Conan, Ran, Sonoko and the Detective Boys are invited to a small island resort for diving lessons. While exploring the island, they find a filming crew lead and directed by Yuuya Miyasaka, an actor who lost his fame due to assault causing the drama he starred in to cancel. When the weather turns bad, they all return to the resort. Later, Miyasaka is found dead in his room. The resort staff, film crew excluding Miki Kitagawa, and Conan's company meet in the lobby to discuss the identity of the murderer. Due to the rooms having an automatic lock when closed, they conclude Miyasaka had let the perpetrator into his room and suspects it to be the work of one of the crew members.
