The story tells of an old man who was fishing alone at sea and had no harvest for several months. Later, he caught a large swordfish, fought with it for two days and two nights, and stabbed it to death with a spear gun. However, he was attacked by a shark on the way back. Although the old man, who lacked helpers and tools, killed several sharks, the swordfish was eaten by other sharks. When he entered the harbor, only a set of bones was left in the swordfish.
