Tenderfoot Burton and his wife join forces with an old prospector to search for the rich gold strike of which the oldtimer claims to know. Along with a couple of noaccount gunslingers, they ride deep into the mountains to find the gold, unaware that the treasure is guarded by an allfemale tribe of deadly, beautiful, and topless Indians.
