Three Without Fear

After a shipwreck, an American boy named Dave is cast ashore on a desolate beach in Baja California. He is found by a Mexican brother and sister, Pedro and Maria, orphans who have run away from a bad foster home. Dave wants to return to his parents in California, while Pedro and Maria want to find their grandmother in northern Baja. Joining together, they attempt to walk north along the length of the Baja peninsula, a journey of hundreds of miles on foot in a sparsely populated desert. Accompanying them are a half-coyote dog named Chico and a roadrunner bird with a broken wing.

They improvise and invent. They hunt rabbits with slingshots and dig up clams on the beach. They endure storms and days without water or food. They are held captive by a bad man. They face these adventures, as the title says, without fear while their friendship grows.
