 In Guatemala, a team leaded by the lunatic scientist Dr. Schroeder (J. Patrick McCormack) gets rare specie of killing wasps by force from some Indians. They hire a drug dealer to bring the insects to Mexico, and provoke an accident with his truck, releasing the wasps. The truck is followed by a snoopy American journalist, Sandra (Kaarina Aufranc), that is covering a matter about traffic of cocaine. In the location, coincidently the American entomologist Daniel Lang (Shane Brolly) is making a research with mosquitoes. When the wasps attack the locals, Daniel sees how dangerous the species is and tries to help the population with the support of Sandra.
