The film began with the search for the valuable and baltimore focus Heart of the Ocean necklace. It was believed by Brock Lovett and his team that the necklace was submerged in the bottom of the Atlantic Ocean together with the Titanic. They failed numerous times until they found a vault which they believe, holds the necklace. As it was lively broadcasted in the television, they opened the vault only to be greatly dismayed for there was no diamond necklace inside. Only a sketch of a naked woman wearing the treasure they were looking for. Lovett was hopeless until he received a phone call from an old woman claiming that she knows who that naked woman was.

Rose together with her granddaughter landed on Lovett's ship. He did not want to believe Rose. Not until she said that she is the woman in the drawing. She began to narrate her story as a first-class passenger in the "unsinkable" vessel.

The flashback started with the arrival of a carriage with Rose DeWitt Bukater, her mother Ruth and her rich, ignorant fiance Caledon Hockley in it. The first class passengers boarded Titanic. At the same time, a young man Jack Dawson won third class tickets for the Titanic in a poker game with his friend Fabrizio.

Rose was forced by her mother to marry Cal to save their downgrading wealth status. Unhappy about marrying a man she doesn't love, she ran to the edge of the Titanic near the propellers, and planned to commit suicide by throwing herself to the ice cold ocean. Luckily, Jack saw Rose trying to jump off from the railing. He successfully convinced her not to jump. "You jump, I jump." he said. As a thank you to Jack, Rose urged Cal to invite him for dinner. After the said dinner, Jack secretly invited Rose to "the real fun". That is in the third class party. They had so much fun and Rose was free to do the things she never got to do with the first class people. They started falling in love with each other.

On the other hand, Bruce Ismay the ship owner proposed to Captain Thomas Andrews to fasten the course of Titanic to gain publicity. And yes indeed. They gained publicity in a different way.

Jack and Rose kept seeing each other on the boat even though Rose's mother disapproved. Rose asked Jack who was an amazing artist, to draw her nude wearing only the Heart of the Ocean. They were enjoying the night until Titanic hit the iceberg. The first to be affected were the lowest part of the ship where the workers were located.

As the Titanic was sinking, all women and children were ask to climb aboard small boats and some less fortunate poor people were left locked downstairs. On the other hand, Jack was framed by Cal for stealing the Heart of the Ocean and was locked down in a room as a prisoner. Rose refused to board the lifeboat with her mother and some first class passengers. Instead, she went back to find Jack. The two fought against odds. They came across with Cal who forced Rose to board the lifeboat and told her a lie that he and Jack have their own lifeboat to catch. While lowering down the lifeboat, Rose just could not bear the thought of being without him so she jumped back to the sinking Titanic.

Cal was so infuriated that he tried to kill them by shooting at them but was unsuccessful. After the ship sank, Rose and Jack were holding each other's cold hands while Rose was lying on a floating door and Jack was freezing by the icy waters of the North Atlantic Ocean. Jack was already dead frozen before help arrived. When Rose got to safety she saw Caledon looking for her and she hid from him. In the pocket of the coat Cal lent her, was the Heart of the Ocean. When she was asked what her name was, instead of saying her true name, she said Rose Dawson.

The film ended with old Rose tossing the Heart of the Ocean overboard. That night she dreamed of being met by Jack on the grand staircase of the Titanic, they kiss and are applauded by those who were lost in the disaster.

The film presented a lot of events but this review will focus mostly on its Marxism approach. In the foremost part of Rose's flashback, the different social classes were already presented. The ship was divided into three classes; the first-class, middle-class, and the third-class. The film however focused mainly on the first-class and third-class. Before entering Titanic, everyone except the first class passengers would undergo a certain lice and baggage inspection. The first class passengers have a different entrance where they don't even have to join with the rest of the passengers and can freely enter without any inconvenience. It was also shown in the story how wrong it was for first-class passengers to mingle with third-class passengers and vice versa.
