Two thugs abduct a beautiful geologist who has been hired to survey a piece of land for its diamond mining potential. After tormenting the bound, gagged and blindfolded damsel, the geologist agrees to submit a false report concerning the tract's value. When Neil learns that his red-headed partner plans to double-cross him, he takes both bound beauties to the evil Mace's house for appropriate treatment. The geologist is released and the red-headed henchman escapes and heads straight to a jewelry store owner's house, where she chloroforms the woman, binds her and attempts to force her to reveal the combination to the safe.
