OK, so it’s 2077, and Earth is not the place to be. Things got really bad here in 2017. Aliens showed up. No, not the secure-the-borders kind, the secure-the-skies kind. People called them the Scavengers. Humans won the ensuing war, but at great cost. The moon was destroyed, as was much of the Earth. The human race now lives on a moon of Saturn.
One of the few people left on the planet is Jack Harper. Maybe “above” would be a better word than “on.” He’s stationed with his lover/communications officer, Victoria, in a slick, sleek command post atop a tower thousands of feet in the air. “We’re the mop-up crew,” Jack says. He goes down below on patrol, keeping an eye on the remaining Scavs and overseeing the extraction of water and other resources from the now largely ravaged Earth. How ravaged? It looks a lot like the planet in “Prometheus,” which makes sense, since Iceland is where both movies did a lot of their exteriors.
