A Latin government official, known only as The Captain is grilling suspected rebel couriers Maria and Dolores as to who they deliver messages to and where are the locations of rebel camps. The fact that the captain is also a beautiful woman doesn't affect her brutal sadistic methods in the slightest degree. The captain uses whips, clothespins, tongs and suspension to force the truth from her clever captives. They know that by holding out just a little longer, the revolution will start at midnight. When it does, there will be excellent chance that the captain will the one in bondage and Maria and Dolores will have an opportunity to pay her back with suffering and humiliation.
