After bringing his beautiful new wife Paula home to America from a remote island on which she was raised, Professor Norman Reed begins to feel the clash between his world of rational science and hers of bizarre dancing and freaky voodoo rituals. Norman's stuck-up friends also sense Paula's strangeness, and soon their meddling gossip and suspicious scheming push the poor woman to use her magic to defend herself and her husband – and maybe even to kill! Or is it just the power of suggestion...?
