Battlefield Earth

In the year 3000, Earth is ruled by the Psyclos, a vicious alien race of which Terl is a member, that has laid waste to the planet, killed the majority of the population, and stripped Earth of its valuable resources. Pockets of resistance remain among the surviving humans; Jonnie "Goodboy" Tyler is one such rebel, living in hiding in the mountains near Boulder, CO. Eventually, Johnny begins organizing like-minded humans for a final stand against the Psyclos.
