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.

During the autumn of 1944, RAF Hudson, carrying a VIP passenger in possession of highly secret information, is shot down and ditches in the North Sea.

The film's title reflects the motto of the RAF's Air Sea Rescue Service, one of whose high speed launches battles against its own mechanical problems, enemy action, time and the weather to locate and rescue the downed crew and the vital secret papers they carry.
