Todd (Kurt Russell) has been trained since birth, through brutal conditioning, to be an emotionless killing machine. After 40 years, Todd and his comrades are deemed obsolete when Col. Mekum (Jason Isaacs) promotes a new breed of genetically flawless soldiers. Discarded on the trash-covered planet of Arcadia 234, Todd is rescued by colonists Mace (Sean Pertwee) and Sandra (Connie Nielsen) -- but he's soon forced to face his stronger replacements when the military seeks to wipe out the colony.
