Women who have been captured and sold as slave labor to a South American emerald mine hatch a plan for revolution and revenge.

At a female prison located deep within the deadly South American jungles, a group of woman are forced to mine for valuable emeralds for the local corrupt government. A group of new prisoners on the way to the jail are ambushed and are convinced to join a group of revolutionaries seeking to overthrow the prison guards and take the treasure of jewels for themselves.

A women's prison camp is located deep in the tropical rain forest. Sadistic guards and a warden from hell make life almost unbearable for the inmates, and any infraction of the rules is dealt with swiftly and savagely. The camp doctor is horrified at what he sees happening, and drinks heavily to push the horror away. Finally the inmates have had had enough, and they enlist the help of the doctor to try and escape.
