Dave Arnold spent decades chasing a legend of lost Spanish gold buried in the Texas desert, guided by an old map that supposedly marked the way. His search centers on a set of carved markers called the Spider Rocks, each stone said to hold another clue pointing toward the hidden cache. The film traces Arnold's decades-long hunt through the string of bad luck that dogged him, including the unexplained death of one of his associates, and asks whether the setbacks were coincidence or something closer to a curse. Interviews and location footage from the Texas desert reconstruct how the legend took hold and why treasure hunters kept returning to the same stretch of land generation after generation. The stones themselves, weathered and cryptic, are the closest thing to physical evidence in a story built mostly on rumor, old maps, and one man's obsession. Whether the gold is real or not, the film leaves Arnold's fate as its most concrete mystery.
