In a dystopian near future, a corporate heist goes wrong and the team members struggle to survive a desperate escape through the apocalyptic sprawl with their stolen prize, a weapon of unspeakable power. As they navigate the urban wasteland, they must contend with barbaric gangs, corporate death squads and the terrifying truth about the weapon they have stolen.

Two convicts, held in an orbiting detention facility above a post-apocalyptic earth, are hired by mega-corporation Hunsinger to perform a risky salvage mission down on the planet. They land, and work their way into a gigantic underground industrial complex, following a map to their ultimate destination, to retrieve and salvage... the item. Being prisoners, they are given little info, and are given credit toward early release as payment. They get more than they expected, and things go from bad to evil.
