The story of the breakout of the German battleship Bismarck—accompanied by the heavy cruiser Prinz Eugen—during the early days of World War II. The Bismarck and her sister ship, Tirpitz, were the most powerful battleships in the European theater of World War II. The British Navy must find and destroy Bismarck before it can escape into the convoy lanes to inflict severe damage on the cargo shipping which was the lifeblood of the British Isles. With eight 15 inch guns, it was capable of destroying every ship in a convoy while remaining beyond the range of all Royal Navy warships.

In 1940, the Royal Air Force fights a desperate battle against the might of the Luftwaffe for control of the skies over Britain, thus preventing an attempted Nazi invasion.

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.
