Doctor Agasa and Detective Boys including Ai and Conan went to Figure Expo to observe some Figures for research of their works. Upon hearing a woman scream, Conan and the Detective Boys rush into a room to find Kitajima lying dead on the floor from a stab wound. Thus the police have to find the culprit who killed Kitajima among the editor who was rude at him, his fiancé who was upset at him, and a fellow artist who owes him plenty and was distant at him.
