The Sporting Girl.

Jonna, a seventeen-year-old aspiring female MMA fighter, is offered a once-in-a lifetime opportunity to be coached by the famous "Gracie brothers" when her local fighting club gets invited to attend a BJJ camp in Brazil. The only thing that stands between Jonna and the chance to fulfill her dream is money, or rather, the lack of it, since Jonna still lives at home with her alcoholic dosser mom. When entering a world after dark, Jonna realizes there are other possible uses of a fit female body. However, Jonna discovers that sometimes there are bruises that are way more painful than a punch to the head.
