When a film crew shooting in the jungle tosses a witch doctor out of the camp as superstitious mumbo-jumbo, the witch doctor disguises himself as a European doctor in order to teach them respect for his abilities.
A future man travels into the past to rule but finds himself sinking into a pit of swamp quicksand. He sees a couple of hunters and tries to control their minds through telepathic communication, but their minds are too primitive. He cannot shout out to them, as their telepathy rendered their vocal chords inert over a thousand years ago. Despairing, he reverses the time direction and deposits himself into the hands of the authorities.
