Infiltration Unit Zeta was built by the government to replace and eliminate targeted enemies. On one mission, however, he learned that the man he was sent to kill was innocent and made the decision not to destroy anymore. Unfortunately for Zeta, the government believes he has been reprogrammed by the organization he had been infiltrating and will stop at nothing to retrieve the renegade synthoid.
On the run from the National Security Agency, Zeta is joined by Rosalie Rowan, a sarcastic, street-smart runaway searching for her family. With Ro's help, "Zee" learns that his only chance for freedom is to find his creator, Doctor Eli Selig.
