German U-boat U-571 is immobilized by a British destroyer. The US Navy submarine S-33 has been modified to resemble a German U-boat to steal the Enigma coding device and sink the U-571.During a storm, the S-33 comes across U-571 and sends a boarding party over. After securing the ship and transporting the captured crew back to the American S-33 sub, the S-33 gets sunk by the arrival of a German resupply sub.

Control of the main ballast tanks is lost and the ship ascends uncontrollably. Tyler orders crewman Trigger to submerse himself in the bilge underwater to repressurize the torpedo tubes.Trigger uses an air hose to enter the flooded compartment. He closes the air valve to the torpedo tubes, but a second leak and broken valve are found, which Trigger can't reach. U-571 surfaces, unable to fire its last torpedo. The destroyer fires on the ship, which is heavily damaged and...
