An old hermit makes a pact with the devil and is resurrected as a young man. He poses as Nick Richards and begins practicing black magic in the hermit's shack. In sinister ceremonies involving sacrificial goats, Nick is able to transform into demonic animals and wreak havoc in a small town. The village sheriff and doctor begin to get suspicious after a series of deaths and are shocked as their horrifying fears are confirmed.

Ed Nelson ("The Brain Eaters," "Night Of The Blood Beast") gives an eerie performance as the Devil's partner in this ghastly tale.
