A beautiful pianist comes to Tokyo for a charity concert - and City Hunter is there. But music isn't his forte. He wants lessons in the language of love.

And diplomatic infighting swirls around the upcoming concert until Nina the pianist and her grandfather Klaus are kidnapped. A maelstrom of exploding grenades, the rumble of Falcon's jeep, and the tinkling of the ivories all set the stage for City Hunter: . 357 Magnum. The show must go on!

Kindaichi, Miyuki and Fumi are invited to the resort of the Deep Blue Island by their senpai Akane, the daughter of the president of the Aizawa Group.
