A seventeen-year-old aristocrat falls in love with a kind but poor artist aboard the luxurious, ill-fated R.M.S. Titanic.
84 years later, a 100 year-old woman named Rose DeWitt Bukater tells the story to her granddaughter Lizzy Calvert, Brock Lovett, Lewis Bodine, Bobby Buell and Anatoly Mikailavich on the Keldysh about her life set in April 10th 1912, on a ship called Titanic when young Rose boards the departing ship with the upper-class passengers and her mother, Ruth DeWitt Bukater, and her fiancé, Caledon Hockley. Meanwhile, a drifter and artist named Jack Dawson and his best friend Fabrizio De Rossi win third-class tickets to the ship in a game. And she explains the whole story from departure until the death of Titanic on its first and last voyage April 15th, 1912 at 2:20 in the morning.
After winning a trip on the RMS Titanic during a dockside card game, American Jack Dawson spots the society girl Rose DeWitt Bukater who is on her way to Philadelphia to marry her rich snob fiancé Caledon Hockley. Rose feels helplessly trapped by her situation and makes her way to the aft deck and thinks of suicide until she is rescued by Jack. Cal is therefore obliged to invite Jack to dine at their first-class table where he suffers through the slights of his snobbish hosts. In return, he spirits Rose off to third-class for an evening of dancing, giving her the time of her life. Deciding to forsake her intended future all together, Rose asks Jack, who has made his living making sketches on the streets of Paris, to draw her in the nude wearing the invaluable blue diamond Cal has given her. Cal finds out and has Jack locked away. Soon afterwards, the ship hits an iceberg and Rose must find Jack while both must run from Cal even as the ship sinks deeper into the freezing water.
