Giant Robo lies in ruins after the magnetic attack on Von Folger's Eye failed. Taiso, meanwhile, confronts his old enemy in an attempt to buy his colleagues more time to escape the doomed city before the Eye activates.

Big Fire's mighty Orb has disappeared, its anti-Shizuma field inactive and Taiso's sacrifice has brought the Experts of Justice some valuable time. Giant Robo, meanwhile, is lost amongst the frozen Himalayan mountains.

Genya returns to Big Fire's secret headquarters with a new plan to put a cessation to the hostilities once and for all. As the surviving Experts of Justice regroup and nurse their injuries, they learn that neither Giant Robo or Agent Gineri are now trusted by Interpol. The Expert's resources are now truly stretched to breaking point, especially after the final attack on Saint Abbe.

Emmanuelle acquires the third sample, prompting both Chief Chujo and agent Ginrei to prepare for the ultimate sacrifice.
