Karin is a brilliant student whose good looks give her an added advantage in assuming the role of a prostitute and exploring Berlin's thriving sex industry. Hired posthaste by nefarious Madame Clavius, the pretty blonde sets about gathering information for her thesis when she discovers that her old friend Madeline has been financing her luxurious lifestyle by working as a call girl in the very same brothel.
