Voodoo Woman 1957

Harry West Norman Willis discovers gold in the idol worshipped by a jungle voodoo tribe in Bantalaya, a French-owned jungle colony. He enlists two treasure hunters from the United States, one of them being the beautiful but ruthless Marilyn Blanchard Marla English. Hoping to take the treasure for themselves, Marilyn murders Harry and steals his map. They con the innocent Ted Bronson Mike Connors into acting as a jungle guide and leading them to the tribe that owns the idol.

Meanwhile, Dr. Roland Gerard Tom Conway, a mad scientist who has exiled himself deep in the same jungle, is using a combination of native voodoo and his own biochemical discoveries in an attempt to create a superhuman being. He hopes that this being, possessing the best of man and beast, will be the mother of a new perfect and deathless race which he will control with a mixture of hypnosis and telepathy. He is accompanied by his wife, Susan Gerard Mary Ellen Kay, who no longer loves Dr. Gerard but is prevented from leaving by her husband and the natives.

Dr. Gerard’s initial attempts to create a female superbeing are a failure because the transformation is only temporary and the native girl used as the subject of the experiment lacks the killer instinct he deems necessary to carry out his instructions. However, when he meets the treasure hunters, he decides that Marilyn Blanchard would be a perfect subject for his experiment. He successfully turns her into an invulnerable monster, but when she learns her quest for gold was in vain, he loses his mental control over her and she destroys him. Ted Bronson and Susan escape in the ensuing chaos.

After becoming human again, Marilyn Blanchard tries to salvage the idol which has almost fallen into a poisonous gas pit which the natives use for their sacrifices, and she accidentally loses her balance and falls into it herself, only to rise up out of it as the beast once again.
