The death initially looks like a tragic accident. However, Conan, ever-observant, notices inconsistencies in the scene. He soon suspects that it was a meticulously planned murder.

The episode begins innocently enough with the Junior Detective League excited about an upcoming meteor shower. Professor Agasa treats the kids to a trip to an observatory, hoping to spark their interest in science. However, as is typical in the world of Detective Conan, a peaceful outing quickly turns into a murder investigation.

As Conan deduces the murder case (a clever trick involving frozen wine and the victim's pet dog), the horror of the Black Organization fades into the background. In the end, Conan discovers that the black Porsche was not Gin’s. Instead, it belonged to a doctor from a nearby clinic who was having an affair.
