Research professor, Dr. Denwell (Dean Jones), receives a mysterious potion from a colleague residing in exotic Bombay. Imagine his surprise when, after sampling the formula, he becomes completely invisible. In the meantime, a sinister force of evil steals a secret formula, called Formula D. from the institute. With Formula D in their hands, the power hungry villans now have the necessary weapon needed to rule the world. With the fate of mankind in his hands, Dr. Denwell (and his trusty companion Dylan) use the exotic disappearing formula to launch an invincible and invisible attack against the evil conspirators.
