Looking for a TV episode where newlywed wife falls under the spell of a devil or magician

[Tim McGregor]

The newlyweds come to a motel and the wife is seduced by the Mephisto/Dracula type who owns the motel. The man wants his wife back and in the final scene, the motel owner opens a closet door where the wife is embedded into the wall and has moving snakes hissing and bobbing all around her and reaching out toward the husband. The motel owner says something like, "You see? She will never leave me!!" and the husband is frozen in shock and then fade to black.
