Yu is a young man who has a past he desperately wants to forget. His present is that he is a superhuman top agent for Arcan, an organization dedicated to protecting ancient artifacts to prevent them from falling into the wrong hands. However, he receives several bloody messages, culminating in the suicide of a friend, telling that Noah would be his death. In response, Yu travels to Turkey to visit the Arcan dig at Mount Arrat, where Noah's Ark is supposed to have rested. Along the way there and at the destination, he learns of forces of his past have returned to stop him and sieze control of the Ark, which turns out to be an alien device of ultimate power. 热血+狂想。遗迹片。有点不知所谓。不喜欢小孩。有点失望～～～。4°c工作室难得的正常向作品。“人类是上帝制造的唯一失败的作品”。不能算“大友克洋自己的作品”，所以不要比较，谢谢。 一个名为“阿卡姆”的民间组织受到远古文明留下的讯息启发而成立。旨在保护及封印超古代文明的危险遗迹。加入“阿卡姆”的特殊工作人员，人们称之为SPRIGGAN。其中实力No.1的特工是一位叫作御神苗优（森久保祥太郎 配音）的十七岁少年。在土耳其的一次调查工作中，“阿卡姆”竟无意地发现了诺亚方舟。方舟隐藏着毁天灭地的神秘力量，于是很多组织都开始窥伺这个传说中的远古遗迹。美国派出了半机械改造人小队与“阿卡姆”展开激烈的遗迹争夺战。而其中一个以神自称的改造人少年竟想私自利用挪亚方舟引发第二次洪水灭世……御神苗优是否能够阻止这一疯狂的计划呢？世界将会走向灭亡吗？
