Zeta and Ro head down south to intercept a drug lord, unaware that the government has sent a new, improved model of the Zeta robot project on their trail.

Zeta and Roe intervene when a local biker gang harasses a child, who is the son of a wealthy robotics manufacturer. When the child is kidnapped after he invited them to his home, Ro and Zee are implicated in the crime.

Zeta breaks into a security base to steal a database containing retinal IDs, then breaks into Cyrobin disguised as a Dr. Wilhelm. His creator, Dr. Selig, is working at Cyrobin. Things go amiss when the real Dr. Wilhelm shows up before Zeta can communicate with his creator and prove his innocence. Selig is caught in a cyrogenic freeze unit when a stray shot shatters the control. With the lab in lockdown, Zeta is forced to remain hooked up to Selig's suspension unit and maintain his life. The authorities are breaking in, so Zeta takes a risk and tries to go into the unit, using his internal heaters to revive Selig. At the risk to his own ""life"", Zeta succeeds, but is forced to flee before Selig regains consciousness. Meanwhile, Agent Bennett is being shut out of the investigation by a mysterious Colonel Lomak, and Agent Lee resigns after giving away Bennett's plans to Lomak.
