Molly

The legend is real

In a post apocalyptic world where bullets have become currency and medicine is rare, a clan of marauders uses a home brewed drug to turn innocent people into rabid beasts to have them fight each other in their fighting pits for their entertainment. When their leader discovers rumors of a girl with superpowers roaming the beach near their fort, he sends his best people out to capture her. Meanwhile, the girl, Molly, has discovered a young child, living alone in a cabin in the wasteland, waiting for the return of her parents, who are probably dead. Molly has to protect the child and fight of the marauders at the same time.
