Three desperate people who had fled Mormon persecution were being held prisoner in a lost canyon. Among them was a beautiful lady named Fay Larkin, whom John Shefford was in love with.

The secret to the canyon lay in a hidden Mormon village of "sealed" wives, where the penalty for trespassing was death. And the treacherous half-breed Shad and his murderous crew were blocking the way to the village.

The tenderfoot Shefford was desperate to rescue his lady. To accomplish this was no easy task, especially considering he didn't even pack a gun. He would have to fight his way to the canyon, knowing that his efforts might end in bloody slaughter.
