Deep-sea explorer Brock Lovett has reached the most famous shipwreck of all - the Titanic. Emerging with a safe believed to contain a diamond called 'The Heart of the Ocean', he discovers the safe does not hold the diamond but a drawing of a beautiful woman wearing it. When Brock is later interviewed on TV, he shows the drawing to the cameras, and a 100-year-old woman named Rose Calvert living in Michigan recognizes the woman in the drawing - herself! On a visit to Brock's explorer ship over the wreck, Rose tells her story of the Titanic and its ill-fated voyage. Engaged to a would-be steel magnate, Caledon Hockley, she boards the Titanic's first-class suites with him & her mother in Southampton. Also boarding are Jack Dawson & his friend Fabrizio, after a lucky poker game wins them tickets in steerage. When Rose attempts suicide by jumping off the stern in 3rd class, Jack pulls her back onto the ship...and a bond is forged between them as Jack is invited by her into 1st-class the following day. Rose's mother & Cal Hockley try desperate measures to keep them apart. But that strategy goes out the window when the Titanic collides with an iceberg, and due to a design flaw begins to sink - despite being proclaimed 'unsinkable'. Now Rose & Jack must fight to stay alive, but is young Jack already doomed because of his lower status as a steerage passenger?
