The planet suffered an environmental collapse. The air became dangerous to breathe, the water became toxic, and billions of people died.
Generations later mankind has finally re-established a rudimentary society, in which bounty hunters roam the land in search of wanted eco-criminals. Bounty hunter Attica Gage (Gina Carano) has a chance at the bounty of a lifetime: bringing down the ruthless outlaw, Thomas Jackson (Ryan Robbins).
Gage infiltrates Jackson's gang, and everything is going to plan until she meets a slave girl that reminds her of her dead sister. With her loyalty to only herself now tested, Gage learns that there might be more to life than just survival.
