A professor experimenting in the paranormal seeks to achieve mind control over his subject to demonstrate the potential of such ability. His subject is his wife who is participating in the experiments while apparently carrying on an affair with one of the professors’ associates. The associate brings along a research monkey for the professor to use for a while. (More about the monkey later, as E. G. would say).
The professor wants to test the extent of this power by getting his wife to do something she wouldn’t normally do in a conscious state.
