In 2065, Earth is infested by alien life forms known as Phantoms. By physical contact Phantoms consume the Gaia spirit of living beings, killing them instantly, though a minor contact may only result in an infection. The surviving humans live in barrier cities, areas protected by an energy shield that prevents Phantoms from entering, and are engaged in an ongoing struggle to free the planet. After being infected by a Phantom during one of her experiments, Aki Ross MingNa and her mentor, Doctor Sid Donald Sutherland, uncover a means of defeating the Phantoms by gathering eight spirit signatures that, when joined, can negate the Phantoms. Aki is searching for the sixth spirit in the ruins of New York City when she is cornered by Phantoms but is rescued by Gray Edwards Alec Baldwin and his squad Deep Eyes, consisting of Ryan Whittaker Ving Rhames, Neil Fleming Steve Buscemi and Jane Proudfoot Peri Gilpin. It is revealed that Gray was once romantically involved with Aki.Upon returning to her barrier city, Aki joins Sid and appears before the leadership council along with General Hein James Woods, who is determined to use the powerful Zeus space cannon to destroy the Phantoms. Aki is concerned the cannon will damage Earths Gaia a spirit representing its ecosystem and delays the use of it by revealing that she has been infected and the collected spirit signatures are keeping her infection stable, convincing the council that there may be another way to defeat the Phantoms. However, this revelation leads Hein to incorrectly conclude that she is being controlled by the Phantoms. Aki and the Deep Eyes squad succeed in finding the seventh spirit as Akis infection begins to worsen and she slips into unconsciousness. Her dream reveals to her that the Phantoms are the spirits of dead aliens brought to Earth on a fragment of their destroyed planet. Sid uses the seventh spirit to bring Akis infection back under control, reviving her. ........
