Milton Buckmaster, who was raised by the Navajos and goes exclusively by the name of Silver Hat, is faced with the difficult challenge of rescuing Lady Grace from the Hopi nation. It all starts when the eastern-educated son of a Hopi chief invites Lady Grace, who has been named Slender Woman by the Navajos, to come and witness the very secretive annual snake dance. Unable to resist, Slender Woman and her father convince Major Doyle to let them go. Major Doyle's worst fears are realized when Slender Woman is kidnapped at the ceremony, and it is now left to Silver Hat, with the help of an old Navajo medicine man, to find and rescue her. All that stands in the way is a large army of Hopi warriors who will not give up without a fight.
