Conan is after the cunning killer imbedded in an outwardly innocent mountain-climbing fraternity, desperately trying to hide deadly secret!

While on vacation, Conan gets involved in a Mystery Tour via Professor Agasa. Someone asks if Kogoro is the Night Baron, a character from Shinichi's father's novels. What is supposed to be an innocent Mystery Tour turns quickly as Conan is pushed off a balcony into a pool. Conan was pushed by the Night Baron! Yet, one more twist happens when someone else is pushed from a great height and is impaled!
