Life on planet Earth has been wiped out by biological warfare, leaving behind only androids. Two of those androids, Martin and Alicia, have a secret project: Cain, a human being grown from the DNA of a single human hair. Martin and Alicia must keep Cain’s existence hidden from the military androids, led by Moloch, a power-mad machine who is determined to stamp out any trace of the human race before it rises again.
