During a shootout in a saloon, Sheriff Hunt injures a suspicious stranger. The doctor's assistant, wife of the local foreman, tends to him in prison. That night, the town is attacked and they both disappear—only the arrow of a cannibal tribe is found. Hunt and a few of his men go in search of the prisoner and the foreman's wife. In the dying days of the old west, an elderly sheriff and his posse set out to rescue their town's doctor from cannibalistic cave dwellers.
