This anime feature film from the director of the acclaimed Appleseed tells a hallucinatory story about a deadly virus that threatens to wipe out the human race, and 160 test subjects are cryogenically frozen while scientists look for a cure. One girl selected for the program, Kazuyoshi Katayama, awakens from her slumber to a lab overrun with plants and monsters, and a nightmare world left for her and six others to navigate in search of survival - and her twin sister.
