Kino, Juana, and their son Coyotito live peacefully in a village in La Paz, near the Gulf of Mexico.
Coyotito is stung by a scorpion, so the family and some of the towns - people go to the city to see the doctor. The doctor,however, refuses to treat Coyotito.
Kino finds the pearl, and when the neighbors and city people find out, they try to take advantage of him.
Kino kills a man who tries to rob him. Before that, he beat Juana for trying to get rid of the pearl. After this, Kino is almost animal like.
Kino, Juana, and Coyotito flee to the mountains in the North because Kino killed a man, and they knew someone would be sent to get them. Three trackers follow them, and one of them mistakes Coyotito's cry for that of a Coyote and accidentally shoots him.
Kino and Juana return to La paz and throw the pearl into the sea.
