Ross Sylibus is assigned to a police unit on a Martian colony, to find that women are being murdered by a psychotic named D'anclaude. He is assigned a very unorthodox partner named Naomi Armitage, who seems to have links to the victims. To stir things up more, every victim is found to be an illegally made third-generation android.

Naomi Armitage and Ross Sylibus have changed their names and live with their daughter Yoko as a happy and normal family on Mars — until an android riot breaks out at an anti-matter plant on Earth.
