When she successfully fends off three thugs trying to rob her, she draws the attention of Shu, a Wudang champion, who is impressed by her raw street fighting abilities. Shu recruits Jane and trains her to fight in the vicious, all-female, underground martial arts tournament known as "The Kumite."

After months of rigorous preparation, Jane is ready to face off against the deadliest female fighters in the world, including Ling, the apprentice of Shu's nemesis, Wai, a Shaolin master. Other nefarious forces also lie in the shadows, taking Jane on a journey through the gritty underworld of Hong Kong as she fights to be named the best female fighter in the world.
