This isn't a real superwoman movie, but I think some of us here might like it since its concept is most used in male dominated films.
A groups of women from various backgrounds are kidnapped and taken to a hidden location and force to fight to death in one on one fights with no weapons.
It stars Rachel Nichols, Zoe bell and Rebbecca Marshal. The actreses do most of their own fighting in close quarters.
Its airing on the Showtime channels this mouth and is even on tonight at 9:05 PM central time on one of them.
