The company "NV M.S.52" hires an experienced monster hunter. The reward is too big to refuse. The goal is to capture dangerous samples that have escaped from the laboratory. The hunter also understands that big money is a big risk. Terrible mutants prowl in search of prey, trying to quench their thirst for blood. They've spent too much time in captivity, and now they're going to take out all their rage on anyone who gets in their way.
