A 40,000-year-old race of snake people resurface, and with help of Serpentor, Desto, Baroness and Dr. Mindbender, plan to eliminate all of mankind and rebuild Cobrala. Once rulers of Earth, the Snake people were driven underground by ice-age temperatures. While in exile, they developed a plant whose spores turn ordinary men into mindless, weak animals. The key to their plan is G.I. Joe's secret project--the Broadcast Energy Emitter. Only this device generates enough heat so that the spores can mature. Humankind's very existance depends on G.I. Joe, but are they strong enough, smart enough, cunning enough to fight a warrior race with 40,000 years of experience?
