Outside London, Dr. Laurience discovers
a way to transport the mind of one person into another. His
discovery enlists the support of newspaper publisher Lord Haslewood,
whom the doctor turns on when the London medical community dismisses
him.
Out of jealousy, Laurience attempts to
exchange minds with Dick Haslewood, the fiancé of Dr. Clare Wyatt.
His plans foiled, Laurience dies as Clare promises to destroy his
invention.
