Plot

An assassination in the Philippines is caught on film by kickboxer Christy, which leads to her death at the hands of radicals intent on disrupting peace talks. Her sister Kat, a Los Angeles police officer, comes to Manila to try and bring justice to the people responsible. She enters the kickboxing tournament in order to get closer to the nefarious agents, and begins unravelling the twisted plan while narrowly evading the wrath of the Death Brigades.
