In 1866, Beautiful archeologist Alison Shaw and her brother, Hammond, arrive in Tucson seeking a guide into Apacheria, where they plan to search for Hohokam artifacts. They try to hire the famous scout Jake Moran as a guide. Jake’s not the hero everybody thinks he is, though, and he wants no parts of a trip into Apache country; so Alison enlists the services of suave French rancher Edouard de Lacey, instead. De Lacey is the secret leader of a gang of outlaws, and he suspects that Alison is really looking for treasure. He intends to steal the treasure and return to France to live in luxury. For Alison, he has other plans. De Lacey is also Jake Moran’s deadliest enemy. He’s been trying to kill Jake for ten years, since Jake led the Vigilance Committee than ran de Lacey out of San Francisco. When Jake learns that Alison and her brother have gone with de Lacey, he has to try and save them. He rescues Alison and her brother, and with the outlaws and Cochise’s Apaches hot on their trail, the three of them set out to discover the secret of Dead Man’s Canyon.
