During Holy Week in Santa Fe, New Mexico, a young boy named Pedro "Peddie" Martinez turns up missing. At Palm Sunday Mass, Father Andy Leary has a sixth sense that a parishioner is involved. When the parishioner comes to confession the next day, Father Andy's suspicions are confirmed. But is the boy's disappearance an abduction for immoral purposes, or something else entirely?

To complicate matters, Father Andy is faced with his weakness of the flesh. He is impossibly attracted to the nun who is principal of their parochial school. Even as he gallantly fights his lust, the nature of their relationship comes to a head as he involves her in the search for Peddie.

But in finding Peddie, Father Andy also finds himself-his real limitations and his true vocation.
