Bette Davis is Madame Sin, a sinister-looking, totally evil, half-Chinese woman who indulges in endless machinations. Ensocnced in a Scottish castle that is packed with an array of spy gadgetry, she runs afoul with counter spy, American CIA agent Anthony Lawrence (Robert Wagner), who is out to counter her plots for control of a Polaris submarine.
Even Doctor No would say "yes" to Madame Sin!
