A series of suicides among high-society matrons coincides with a bizarre jewel theft by a towering Indian who mysteriously disappears when cornered. Kolchak investigates and finds that the Indian is a "diablero," a cursed cliff-dwelling Indian medicine man condemned to walk the earth gathering an eternal horde of jewels. The diablero can change shape into the form of a coyote or crow, and hypnotize anyone with its eyes. Carl must seek the diablero in the highest place he can find, and turn the power of its eyes against it. (thetvdb.com)
