Charged with recovering a sacred relic for his La Paz diocese, Morty Martinez hunts down a gold ring that rests on the finger of New York City billionaire Robert Tyson Grant. The holy quest lands Morty squarely in murderous cross plots between the billionaire and his tabloid-prone stepdaughter, Purity. Grant's conniving girlfriend, a decapitation-happy hit man, and an avaricious fortune teller have their own agendas that put Morty at the center of a sensational murder trial in Mexico. All as told by Morty the night before his execution.
