The sinking of the Titanic is presented in a highly realistic fashion in this tense British drama. The disaster is portrayed largely from the perspective of the ocean liner's second officer, Charles Lightoller . Despite numerous warnings about ice, the ship sails on, with Capt. Edward John Smith keeping it going at a steady clip. When the doomed vessel finally hits an iceberg, the crew and passengers discover that they lack enough lifeboats, and tragedy follows.
