H.G. Wells' the Invisible Man

After an English Family is gunned down while on vacation, Peter accompanies diplomat Zena Fleming to the small Mediterranean state of Bay Akim to prove they're in the gun running business. Having made enemies there, a hoodlum walks into her room and orders her at gunpoint to leave on the next flight. The henchman works for the Citrus Export Business, which she and Peter believe is a front for the country's illegal arms trade. The two sneak onto the premises to investigate, but her life is endangered when she is kidnapped.
