An engineer creates the ultimate weapon in a battle against aliens, only to be suspected as an alien himself. In this psychological science-fiction thriller, set in 2079, the Earth lies under a series of electromagnetic force-field domes, the result of a protracted war with an alien planet. Gary Sinise plays Spencer Olham, a successful weapons scientist who becomes an object of suspicion. Relentless, brutal investigator D.H. Hathaway (Vincent D'Onofrio) is convinced Olham is an alien spy, a simulated human with a time bomb implant. Soon a fugitive, he has to prove his innocence with the help of his wife, Maya (Madeline Stowe), and an underground rebel named Cale (Mekhi Phifer).
