In the sleepy river town of Puerto Diablo, somewhere at the end of South America, a tall stranger arrives to threaten the peace of the natives, the villagers, the local outlaws, and Father Joseph Black, a strong and fierce man of God known as the Black Priest. Influenced by the stories of Hemingway and Peter Matthiessen, it is a tale of choices made, and not made, and the ends they lead to, for good or evil.
