Conan and his friends discover Harawaki's body at the filming location of a zombie movie. On his smartphone is a video of Harawaki drinking hydrocyanic acid. Because only Harawaki was able to drive and there is no cell phone service at the cottage, they are unable to call the police. That night, the bedridden Kogoro tells Ran and Kazuha that zombies have surrounded the cottage. The girls do not believe him, but then they are attacked.
