Before the end of the world, she has some people to kill.

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.
