After the death of Marcel, Paul Lavond sees the chance to use the miniaturization process as instrument of vengeance and he travels to Paris with the insane Malita disguised of Madame Mandilip, a nice old lady and owner of a dolls store. Paul Lavond, using the identity of Madame Mandilip, befriends his resented and estranged daughter Lorraine Lavond and plots a scheme to revenge and vindicate his family name.
