The Devil's Partner

"In this occult obscurity, an old hillbilly named Pete Jensen (Ed Nelson) makes a pact with the Devil and returns to the town of Furnace Flats, NM, as a much younger man. Claiming to be his own nephew, Nick Richards, he romances pretty Nell Lucas (Jean Allison). Her fianc?e David (Richard Crane) is mauled by his own dog, leaving him scarred and bitter. Doc Lucas (Edgar Buchanan) and Sheriff Fuller (Spencer Carlisle) figure it out and shoot Richards down after he turns into a snake and a horse."
