Muay Thai martial arts master Tony Jaa returns to deliver a bone-breaking barrage of knees and elbows in this action opus that finds the star not only delivering blows in front of the camera, but calling the shots behind it as well. Despite the title's indication of this film as a sequel to 2003's Ong-Bak: The Thai Warrior, this movie has no narrative connection to the events of the earlier work, despite the fact that both films star Jaa.
