Alone they are unbeatable... Together they are invincible

A number of fighters are invited to DOA, an invitational martial arts contest. They travel to the tournament island by plane, until they have to jump out mid-flight with parachutes, and then have until sundown to reach the main island to be entered into the tournament. Fighters are then pooled against one another in a knock-out style tournament. The plot revolves around four female fighters who begin as rivals, but subsequently find themselves teaming up against another force.
