A dynamic and emotional story of fighting, passion and sacrifice. From 2016 to 2018, the filmmakers accompanied Joanna Jedrzejczyk, a multiple UFC champion, who at her time conquered the world of female MMA. To stay on top, the Polish fighter has to constantly confront her opponents and her own body, which is forced to make superhuman efforts over and over again. "Invincible" reveals the behind-the-scenes fights of modern gladiators, bluntly showing the blood, sweat, tears and overwhelming loneliness that are the price of the road to success in sports on a global scale.
