Three country singers (Ferlin Husky, Joi Lansing and Don Bowman) are on their way to Nashville, to avoid a storm they stay in what appears to be an abandoned house. However, the house is really the secret base of a bunch of spies (John Carradine, Lon Chaney Jr, Basil Rathbone and Linda Ho) plus an unconvincing man in a gorilla costume. They have a basement torture dungeon and are after a secret formula at a nearby missile plant...
The spies try and scare the country singers away with a collection of rather lame "ghosts". Though there is a real ghost in the house which stirs the pot a bit...
A very strange film, at times so unbearable but at the same time so watchable. Country tunes (some of which are pretty good) are thrown in seemingly at random and with little real justification with respect to the plot. Don't expect many scares, but do expect some real oddness and awkwardness.
This was Basil Rathbone's penultimate film (and his last in English) and he co-starred with Merle Haggard. A terrible film and great at the same time.
