The Devil's Partner is a low-budget black-and-white rural horror film with an unusual story line. Although it's more soap opera than shocker, there are several goat sacrifices, a wino is trampled by a Satanic black horse, and Nelson performs wacko rituals on a blood-smeared hexagon. Byron Foulger steals the show as an easily spooked wino, and director Charles R. Rondeau (The Girl in Lovers' Lane) keeps things interesting throughout. Not bad at all.
