Yvonne Moyer is locked up in the county jail, fighting murder charges the system already decided she's guilty of. It doesn't matter that she killed in self-defense. All that matters now is staying alive to stand trial.

Inside, she's exposed to jail politics and pressure from other female inmates. Her only real ally is Vanessa, a ride-or-die chick who helps her learn the ropes. They hold each other down. But nothing comes easy in an environment where the hand that feeds you also wants to bite you.

While Yvonne fights her legal battles, another struggle unfolds on a remote island where her father Jamie Moyer and other plane crash survivors battle for existence. The crash was orchestrated to eliminate witnesses, but Jamie, his friend Cliffy, and surprisingly, the very DEA agents who tried to kill him, find themselves as allies against the island's dangers. As deadly wild boars hunt them and supplies dwindle, survivors die one by one, testing Jamie's leadership and forcing every survivor to decide how far they'll go to stay alive.
