The Sea Wolves (1980)

This film is based on the true story of a British ship’s plan to disable Nazi radio signals during the heart of the European theater of conflict in World War II. The Allied effort is led by two daring and courageous British intelligence operatives, Colonel Lewis Pugh (Gregory Peck) and Captain Gavin Stewart (Roger Moore). This mission also carries the danger of being illegal, as the Nazi ship resides in neutral waters, British involvement must be denied. The men formulate a plot to disguise themselves as fishermen and to board the Nazi ship where they hope to complete their mission, which will turn the tide of the entire war.
