Why We Fight follows three Toronto-based martial artists whose fights inside the ring mirror the battles they face beyond it. Olivia Bahsous, a teenage Muay Thai world champion, trains under her father in a relationship where love and ambition collide. Sara Bailey, the fastest Canadian in history, male or female, to win a boxing world title — navigates the intensity of being coached by her husband. And Cesar Bonilla, 40, returns to MMA after losing his brother and overcoming addiction for one final shot at glory.

A film that captures the relentless pursuit of excellence, the sacrifices required to reach it, and the discipline, ambition, and perseverance that drive athletes to push beyond their limits.
