A prison psychologist (Charlotte Austin) and psychiatrist (William Hudson) investigate the suspiciously high number of women dying of heart attacks in a prison. They discover that the people running the prison are 200 years old and survive by draining the life energy of the girls. The science behind the plot is nonsense and the acting is not great, but it is a fun piece of 1950's nonsense.
