After the brutal murder of their friend and employer, Matt Stone and Spider McCaw are determined to locate the culprits. Their search leads them to a outlaw hideout, high in the mountains.
The area is called Death Mountain by locals, because no one attempting to pass has ever come back. However, after a running gun battle with the gang, Matt and Spider believe they have located the specific spot of the hideout.
The two friends have to contend not only with the perilous mountain heights, but also with a terrifying menace in a narrow canyon which is capable of stopping anyone who dares to enter. Can they survive the treacherous journey and bring the killers to justice?
