This episode opens with the QEII in the mid-ocean east bound from New York to her home port of Southampton. In the 1920s and 30s the Atlantic greyhounds returned to the ocean, as glorious hotels and ships of state. And when a new war presents greater and more difficult problems on the Atlantic battlefield, it will inspire the great ships to serve their finest hour - some will become legends in their time. This then is the continuing story of the great floating palaces of the North Atlantic.
