It's about a guy stranded on the moon for three years, like a Robinson Crusoe kind of guy. He's mining a product called helium 3 on the surface of the moon for fuel for the Earth, an energy source. Then he meets his clone, and they have to deal with each other. So it's sort of an homage to Silent Running and a little Blade Runner, as far as the replicants and stuff. It's like that, but it's a very simple kind of Robinson Crusoe story.
