84 years later a 100-year-old woman named Rose DeWitt Bukator 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 Cal 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.
Brock Lovett este un cautator de comori si incearca sa recupereze vechi artefacte impreuna cu echipa sa de pe epava Titanicului, un vapor urias care s-a scufundat in Oceanul Atlantic in 1912, dupa ce s-a izbit de un iceberg. Lovett cauta diamante si pietre pretioase, dar descopera un portret al unei tinere fete care nu poarta altceva decat un colier. Cand Rose, in varsta de 102 ani, spune ca ea este tanara din portret, actiunea se muta in 1912 in Southampton, unde pasagerii se urcau la bordul navei Titanic. Printre ei se aflau tanarul Jack Dawson si Rose DeWitt Bukater, care se intorcea in Philadelphia cu logodnicul ei, Cal Hockley, un instarit om de afaceri. In timpul calatoriei, Rose se indragosteste de Jack, iar Cal incearca sa se razbune. Intre timp, Titanicul se ciocneste de un iceberg si apa navaleste in compartimentele din fata. Cal continua sa-i urmareasca pe Jack si pe Rose, iar in tot acest timp uriasa nava isi incepe coborarea catre adancurile oceanului.
