 A psychic is called in to find the location of a burial site near the California-Mexico border. Numerous illegal immigrants are found at the site, murdered by a mysterious killer who leaves religious symbols at the mass-grave. Charlie, who becomes involved in the case by discovering the perfect application of mathematics to help solve Don s case, takes exception to the idea that a man of mathematics could be beaten to the punch by a psychic and decides to informally challenge him to find the girl first. By using both mathematics and the "pseudo-science" of ESP, can the FBI find the missing girl before she too falls victim to the serial killer?
