Horror, comedy, and country corn combine when country singers Woody Weathrby and Boots Malone get caught in a big storm en route to the Nashville Jamboree and end up taking shelter in a creepy looking old mansion that is said to be haunted. Though plenty of spooky things go on there, the hapless hayseeds quickly figure out that the haunting has more to do with a ring of international agents led by the enigmatic and sly Madame Wong than it does the supernatural. The spies have made the abandoned building their headquarters as they endeavor to steal a valuable atomic secret. This was the final film of Basil Rathbone. It is also a sequel to Las Vegas Hillbillies (1966).
