Seven Footprints to Satan on AllMovie

In this curious film, a knickknack collector falls in love with the daughter of a jewel collector. When a rare stone is swiped from a reception at the latter's home, the daughter and her sweetheart begin looking for it. As they drive to the police, they are taken upon a most circuitous path until they end up at the home of Satan, wherein many strange people dwell. The couple is befriended by a helpful dwarf. They must all attend a masquerade ball, and there some of Satan's minions abduct the woman and demand that she produces the jewel, lest she be tortured. Both she and her love then must endure a number of terrifying encounters before they can escape. Unfortunately, the bizarre ordeal has rendered them both stark raving mad.
