In a mystical land torn apart by civil war, a warrior princess must team up with a rival warrior prince to hunt down an evil sorcerer who has summoned a giant flying demon which is terrorizing their land.

Police lieutenant detective Thomas 'Thom' Randall's steady girl-friend, Dr. Jennifer 'Jen' Allen, is Dr. Aaron Michaels's main assistant on his pharmaceutical firm Bellion's research program to cure the highly contagious, fatal infection Guinin. A convicted murderer, whom Thom arrested, is one of their special drug test subjects, but escapes. The convict and Jen are affected by radioactively altered DNA from an experimental reactor used on mosquitoes which transfer quinine. The convict soon mutates into a mosquito-like monster, which sucks its victims dry. By the time Thom and his junior murder brigade partner Charlie Morrison figure out what happens, Jen starts mutating herself.

After an experiment to make the ultimate weapon goes wrong, a team of commandos is sent into a genetic research lab and end up getting stalked by a creature that looks a lot like the Predator
