Steve Saint was five years old when his father, missionary pilot Nate Saint, was speared to death by a primitive Ecuadorian tribe. In adulthood, Steve, having left Ecuador for a successful business career in the United States, never imagined making the jungle his home again.

But when that same tribe asks him to help them, Steve, his wife, and their teenage children move back to the jungle. There, Steve learns long-buried secrets about his father's murder, confronts difficult choices, and finds himself caught between two worlds.
