Convict 762 (1997)

"The more he kills the stronger he gets!"

A spaceship with an all female crew runs into a meteor field because of a navigational mistake. They lose a lot of their fuel and realise they cant get home on what they've got. They are forced to land on a planet which has been reformed into one of the most dangerous penal colonies in the universe in order to refuel. Once there they realise only two men are left on the planet and they are engaged in hand to hand combat. The women cant figure out which one of the men is the officer and which one has systematically slaughtered the rest of the inmates. One by one each of the women is killed. Just who is Convict 762?
