The Mad Monster

“The blood of a wolf he placed in the veins of a man... and created a monster such as the world has never known!”

Petro (Glenn Strange), the simple-minded handyman on the estate of Lorenzo Cameron (George Zucco), is changing, and nobody on the grounds can say how. Cameron is a scientist whose theories his colleagues have laughed at, and he has found a use for Petro that will prove them sound and settle old scores. Sam Newfield, working fast and cheap at Producers Releasing Corporation, shoots it in black and white.
