Anasazi

Professor Lovestock, an English researcher who came to the southwestern United States to study pre-Columbian civilizations, meets Link Miller, a man who a few months earlier had fortunately discovered an abandoned pueblo in a hidden valley. Lovestock is convinced that the necklace that Miller unearthed in that place belongs to the ancient disappeared Anasazi people and decides to prepare an archaeological expedition. During the journey, however, the men of the expedition clash with young Hopi Indians who do not take kindly to white men trampling on the tombs of their people's ancestors. The ambitious warrior Tumak is determined to carry out a massacre to reclaim the sacredness of the place and the rights of its people. Tex, called into question by the sorcerer Tasupi, will have to prevent blood from flowing in the valley Tumak and his followers set out in earnest for the hidden pueblo of Avatay, with the intent of settling scores with the men of Professor Lovestock's caravan. Tex, supported by the wise and peaceful Hopi chief Tuwa, tries in every way to prevent the young and impetuous warrior from being able to avenge the death of two of his men. Helped by his pards, the ranger tries to anticipate Tumak's moves, trying to intercept him before he commits a massacre. Meanwhile, the archaeological expedition manages to reach the ghost village of the Anasazi where a dangerous hunt begins for the "sacred chamber" in which a fabulous treasure is supposed to be hidden.
