After 84 days of poor fishing, the old fisherman, seeing off a young boy who adored him, went out to sea alone in a small boat. Soon after, he felt a big fish on his fishing line. The old man has a mortal duel with a huge marlin he has never seen before, and the sea puts him to the test even further. The author's mature brushwork depicts the human spirit that never gives in despite being tossed about by the threat and harshness of nature. This is a literary achievement that brought the author the Nobel Prize in Literature, and an eternal masterpiece.
