Even under the protection of the Ultraman called Tiga, the Earth can barely sustain itself against the perpetual pounding of one monstrous menace after another. When Tiga suddenly goes missing in action, though, mankind quickly finds itself facing an early extinction. To make matters worse, an alien presence has infected the upper echelon of Japan's government and its sights are dead-set on dismantling the Global Unlimited Task Squad. This could be lights out for the human race! Continuing the adrenaline-charged series from Hong Kong.
