Early in 1915 an experiment took place in the Firth of Forth of a C class boat being towed submerged by a powerful tug. The submarine was towed along at various depths, using a towing slip to enable her, at the opportune moment, to release herself and so make the attack. It was C27 which carried out these experiments which proved quite a success, she and C19 were sent to Aberdeen for actual operations.
A special group of navy divers is created when a disabled Nazi warship is discovered in a fjord in Norway. Commander Bolton (James Caan) is the Canadian expert designated to train the new unit. Their mission is to plant a bomb on the warship as it undergoes repairs. The hard-driving Bolton encounters resentment from the British soldiers he trains, but he ultimately earns their respect as a leader. Their intense training operation is interrupted by an attack of Nazi paratroopers just before the unit leaves for Norway. Spectacular underwater photography is seen in this World War II adventure story based on an actual mission
