The parts from the IR hunter unit, that were destroyed by Zeta in a hospital, find their way into the hands of a young boy who likes to build things. The boy, Jace, accidentally activates the primary chip and the IR unit proceeds to rebuild itself from scratch. Zeta gets wind of the unit's activation when he notices the shipment of parts under the unit's ID. Tracking it to Jace's house, Zeta and Roe end up fighting the unit, and with Jace's help Zeta removes the primary chip and deactivates the unit.
