On the run from the NSA former robot assassin Zeta saves the life of a teenage runaway Ro Rowan. In return, Ro helps him escape the NSA. She persuades Zeta to search for his creators, since they would be able confirm his innocence.

Zeta and Ro break into an NSA depot used to store holograms/robots. They spot Professor Zelig, who downloads information and leaves. The two follow him to a steel yard where he is revealed to be Professor Edmunds, who worked on Zeta's hologram projectors. He is being blackmailed by Sweet, the head of Brother's Day, an anti-tech terrorist organization. They get Edmunds to work with them to lead them to Selig, unaware that Brother's Day has followed them to the hologrammatically concealed floating fortress where Zeta's creator is working to create semi-organic synthoids. Sweet plants an explosive as a disguised Zeta confronts his creator who confesses he secretly planted a "conscience chip" in Zeta (which Bennett overhears). Sweet triggers the explosion before Zeta can reveal who he is. Sweet shoots the escape pod with Selig as he escapes and the scientist is believed dead.
