Titanic is about the romance of Rose DeWitt Bukater and Jack Dawson. The two belonged to two different social classes, but even this wasn’t enough to keep them apart when they met on the Titanic departing from Southampton on the 10th of April 1912, going against Ruth, Rose’s mother, and Cal, Rose’s fiancé at the time. They tried to stay together when the iceberg tragedy happened.
After the ship sanked, they found rescue on a wooden board but wasn’t enough for them so Jack decided to stay in the water. Rose tried to hold on him until the end but his death was inevitable due to the cold temperatures, so she had to let him go.
When all the rescued arrived in the USA, Rose used this opportunity to start a new life with a new name to detach herself from her previous life.
