On the way home from a school trip, three teenagers get trapped in a tunnel as a result of a fatal accident. They're soon assaulted by a "sinister force" that lurk there. When they finally escape the dark tunnel, they find out about the horrific truth... Tokyo, as they have known all their lives, doesn't exist any more. In a strange New World of post-apocalyptic Tokyo, they must struggle to survive the onslaught of the unforgiving environment. The sci-fi 2003 blockbuster is based on a best-selling manga comic by Minetaro Mochizuki. Extras: an all color booklet, and more. Also comes with a bonus disc containing making-of featurette, and more.
