The movie opens with an incident that sparks Kom's interest in self-defense. Her first visit to a boxing gym, her initial interaction with a trainer, and her first steps toward becoming a boxer are portrayed, showing how Kom struggles to balance her home life and responsibilities with her growing passion for boxing. She is forced to make various sacrifices in order to pay for her training and equipment. Kom's first unsanctioned fight is against a heavily favored opponent. She is primarily motivated by a desire to win money so that she can provide for her family, and joins the women's boxing federation and marries a man named Onler, stepping away from the sport to give birth to twins. She has to balance the demands of her training with the needs of her young children, which is made possible by the support of her husband. Under increasing pressure to quit, Kom makes a final comeback, winning the World Championships in 2008.
