Deep in the heart of the Caplock Mountains of Nevada a frightening new horror is preying on settlers and prospectors alike. When the entire crew of a mining outfit is found torn to pieces, the US Cavalry is sent to investigate under the command of General Sherman, the famous Civil War tactician. He immediately recruits his former army scouts turned cowpunchers, Durken and McFee, to help ferret out this new threat to frontier settlements.
Soon the two cantankerous saddle-mates find themselves caught up between government agents and frightened Indian tribes who warn of an ancient evil returned to plague the white invaders; warriors capable of transforming themselves into beasts!
Once again Fred Adams Jr. delivers a gripping weird western that combines the best elements of both western and horror genres to deliver a non-stop action-adventure that will have pulp fans listening eagerly.
