For ages, people were unaware of the sinister plot brewing among mosquitoes - the common bugs were gradually gathering DNA information until they evolved into humanoid beings, immune to conventional weapons and possessing all of humanity's knowledge. The result was catastrophic, with the mosquito population exploding to over a trillion and nearly wiping out humanity, leaving only five thousand survivors. However, there is a glimmer of hope in the lost research of Dr. Kim, who foresaw the insect mutations and built a bunker within mosquito territory. Now, led by elite soldier Kisses, the remaining human forces launch a final assault to overturn their fortunes and engage in a battle for the ages against their evolved insect enemies.
