Melanie Ballard (Natasha Henstridge) is a hard nosed police chief in the year 2025. She and a police snatch squad are sent to Mars to apprehend a dangerous criminal James Williams (Ice Cube). Mars has been occupied by humans for some time and they have set up mining facilities. The mining activities on Mars have unleashed the spirits of alien beings who gradually possess the bodies of the workers. It soon turns out that catching the dangerous fugitive takes a back seat as the alien spirits begin to rid their planet of the ‘invaders’.
Three tales are told, each one increasingly terrifying. The first tells the story of a woman being stalked by an axe-weilding maniac. The second is the story of a man who pays the ultimate price for a beautiful head of hair. The final tale shows what it is like to see life through the eyes of a killer.
