Everyone in the Never Summer Mountains knows about the ancient Indian curse on Skull Canyon. That s why most folks stay clear of the forbidding chasm that sits up in the highest, remotest reaches of the range. But when a pack of savage riders pours into the canyon, apparently searching for something they re willing to kill to keep others from finding, Lonnie learns the extent of Skull Canyon s horror. The young man, lured into the canyon to help a dying rider, is accused of murder himself and sentenced to hang. He escapes and heads back into the canyon with his girl, Casey Stoveville. Since all the current trouble in the mountains started there, it s in the cursed canyon it must end.
