The Big Bend of Texas is a mysterious place in 1869. Legend has it that there's a lost gold mine in the Chisos Mountains. Twelve-year-old Fish Rawlings and his cousin Gid have heard all about it. To find it, they must cross a desert prowled by Apache warriors. They must ride a trail haunted by devil animals and Indian spooks. Even with the help of a young Apache boy, the journey won't be easy.
