High School Girl Detective Suzuki Sonoko Conan, Ran and Sonoko went to the park for stargazing. Looking through the binoculars, Sonoko spotted a hand among the flowerbeds. They arrived at Sasaki Studio; however, there is no corpse at the flowerbed. The director informed them that there is another flowerbed on the roof of Yoshimura building. They went to check but were still unable to find the corpse. Sonoko realised they missed out searching for a spot and went back to Sasaki Studio. Conan also figured out the trick used and who the true culprit is. Conan and Ran rushed to save Sonoko who confronted the culprit. This is the first case Sonoko solved on her own.
