A group of five medical students take on the task of conveying the "voices of the dead". Kaji Daiki fails to get into a popular heart surgery seminar but is somehow accepted into a seminar on forensic pathology. When he approaches professor Sagawa and asks him why he ended up in the seminar, Sagawa challenges him by asking why he wants to study heart surgery. Daiki replies that medicine is meaningless after the heart stops, but Sagawa counters that medicine also applies to the dead.
And so, together with fellow students Ryosuke, Kanako, Teppei and Akira, Daiki begins to explore the mysteries of death.

一组的5个医学院学生承担任务，传达了“死亡的声音” 。卡卓卡大树未能进入很热门的流行心脏手术，但进入了一个法医病理学研讨会上。当他问到，并要求教授萨格瓦解释为什么会在研讨会上，萨格瓦挑战的问他为什 么，他希望在研究心脏手术。大树答复说，心脏停止之后药品是毫无意义，但萨格瓦也说到，药品也适用于死。
因此，加上同学介，加奈子， Teppei和彰，大树开始探索神秘的死亡。
