In the distant future, several colonization ships journey to Pandora, a planet on the edge of the galaxy. The colonists are drawn to the planet in search of a better life and the prospect of striking it rich by claiming the vast deposits of mineral resources rumored to be there. After finally arriving, the colonists discover that the planet is barren of anything of significant value other than deteriorated alien ruins scattered across the land. Those who can afford to do so leave Pandora, and those who remain revolve around chaos and lawlessness.Some of the settlers seek to get rich quick by discovering alien technology, but most others are just trying to survive. After seven Earth years, Pandora's orbit brings it to the transition from winter to spring, and many horrifying creatures emerge from hibernation.
