The American destroyer USS Bedford (DLG-113) detects a Soviet submarine in the GIUK gap near the Greenland coast. (Specifically, they are in Greenland territorial waters at the entrance to the J.C. Jacobsen Fjord, which is due northwest from Iceland.) Although the U.S. and the U.S.S.R. are not at war, Captain Eric Finlander (Richard Widmark) harries his prey mercilessly, while civilian photojournalist Ben Munceford (Sidney Poitier) and NATO naval advisor, Commodore (and ex-World War II U-boat captain) Wolfgang Schrepke (Eric Portman), look on with mounting alarm.

Opening from his point of view, a murderer looks around the city of Amsterdam at night through the canals the city is famous for. He sneaks into a Chinese restaurant's backdoor and steals a butcher knife while the cooks weren't looking. The killer finds his first victim in a local prostitute, who after refusing advances from a cab driver, gets thrown out of the cab. A baglady watches from a distance as the killer plunges the knife into the hooker and drags her back into the water. The next morning, a tour boat on the canal collides with the body of the prostitute, who has been hung on one of the small bridges. As the tourists scream, the body drags on the top of the boat until an opening shows her bloodied body and face.
H. L. Hunley takes his ship, the H.L. Hunley, out in the Charleston, South Carolina harbor and it sinks with all hands. As the blockade still needs to be broken, Brig. Gen. P. G. T. Beauregard has the ship raised and puts George E. Dixon in charge. He starts looking for a crew and after some difficulty, finally finds enough volunteers to man it. They practice cranking the propeller. The crew don’t all get along with each other. Dixon flashes back to the Battle of Shiloh, where a gold coin given to him by his wife (who was later killed in a steamboat explosion caused by a drifting mine), deflected a bullet and saved his life. They take the ship down and sit on the bottom to see how long they can stay down and almost get stuck. The Union navy is warned about the sub. The crew votes that if after an attack they are stuck on the bottom, they will open the valves, flooding the ship rather than suffocate. They go out to attack the U.S.S. Wabash, but the attack fails. Following the warning the ship has draped metal chain netting over the side. Also the rope which was attached to the ‘torpedo’ they were to release under the ship gets loose and becomes entangled in the propeller. It has to be cut loose while sailors on the Wabash shoot at the Hunley. Beauregard proposes putting the torpedo at the end of a long spar. The USS Housatonic is ordered to change its position in the harbor and always be ready to steam, meaning it can’t hang metal netting over the side. The second in command Lt. Alexander is ordered to Mobile, Alabama and a young soldier who had been volunteering to join the crew is allowed to do so. On February 17, 1864, the C.S.S. H. L. Hunley sails out and attacks the U.S.S. Housatonic. The torpedo is rammed into the side of the ship. It blows up and the Housatonic is the first ship ever sunk by a sub. A bullet from the ship breaks a window in the conning tower and wounds Dixon. The explosion opens the seams on the Hunley and it takes on water. It settles to the bottom and they can’t release the ballast or pump the ship. As agreed the crew opens the valves and the ship floods, killing the entire crew.
