“Underdog” (2019) is a powerful sports drama directed by Maciej Kawulski, set in the brutal and demanding world of mixed martial arts. The film follows Borys “Kosa” Kosiński, a top MMA fighter whose promising career collapses after a single mistake during a decisive fight against his greatest rival. Overnight, he loses his title, reputation, and sense of purpose.

Stripped of everything he once defined himself by, Borys is forced to confront his inner demons, past failures, and the emotional consequences of his downfall. As he struggles to rebuild his life, he faces physical pain, public judgment, and personal loss. The journey back is not only about returning to the cage, but about reclaiming dignity, earning respect, and rediscovering love.

Blending intense fight sequences with emotional depth, Underdog is a story about resilience, second chances, and the true cost of ambition — proving that the hardest battles are often fought outside the ring.
