After 84 days without catching a fish, the old man Santiago feels cursed and isolated in his village and within himself. Only the support of young Manolo and the legendary example of Joe Di Maggio give him the strength to return to the sea. In his battle against a giant marlin and later sharks, Santiago discovers his inner courage, which justifies his life. At the end of his career, Ernest Hemingway revisits the core themes of his work in a symbolic narrative that echoes the great models of American literature like Moby Dick.
