In the year 2009 there is an outbreak of violence in a lunar penal colony, after which inmate Adrian Dunn is found dead, mysterious oozing scars on his face. When his coffin arrives on Earth for burial it is discovered to be empty. Boston cop Cameron Grayson, who sent Dunn to jail, sets out to track him down. Sure enough, he soon finds a girl in hospital bearing all the hallmarks of an attack by Dunn. However, strange tumours begin to appear beneath her skin; could she be the victim of an extra-terrestrial plague?
