In 1935 west Texas, two teenagers-Duane McCathern and Tony Picano-decide to go search for a lost treasure of Confederate gold based on an old tale told by a retired Texas Ranger, involving Indians and a mysterious spirit. As their hunt starts, another boy, a long-time rival, finds them in a cave and they must reluctantly include him in their hunt, It doesn't take them long before they realize they need more help so their new partner brings in someone, an A. B. Conway, that he says has the expertise and the skills they need to get the gold they believe is hidden in that cave. The only problem is that A. B. Conway is Abbie. Tony is at once smitten and Duane is clearly annoyed. Once they get the hunt underway, Abbie proves her skill at fabricating machinery is beyond their expectations. And that is a good thing as the hunt suddenly takes an unexpected turn as all of them begin to have out of body experiences and they run into other supernatural problems. As they get closer to the gold, the problems mount and Duane and Tony start showing signs of stress. Then things really start getting strange as all four start having visions of the past. A spirit from the past begins influencing their actions, leading Duane in one direction and Tony in another. As both the distant and the recent past begin to reveal themselves, all of them must make decisions that will have long lasting results. Abbie has to choose between Duane and Tony, and Duane must choose between Tony and Abbie. Who, if any, will make it out of the cave and who will make a deal with the Devil.
