Asten sends Quincy and Sam, at the request of Archbishop Vallejo, to San Remos, Mexico. They are sent to a small village where a young woman is seemingly curing people of their illnesses. She says that she gained her powers from some bones she found in a cave. Quincy and Sam have to join a group of eminent scientists trying to determine how old the bones are and whether they could possibly belong to a legendary missionary from the time of the Incas.
