This is basically a remake of the Universal film "Invisible Man Returns". A man is accused of murder and sentenced to 99 years in prison.
His brother is a scientist and he develops a serum that can render someone invisible. He gives it to his brother who proceeds to simply walk out of jail. He now must prove his innocence so he can be legally released from jail.
The drug has one side effect and that is a slow, creeping insanity that finally takes the man over. he decides he does not want to be visible again, he wants to terrorize the city and become a God.
This is a well acted film with some pretty good special effects and VCI gives us both the Spanish language version and the English version. This has been a hard one to find for a while, but thanks to VCI it is again available for the masses.
