This action-packed World War II thriller shows a U.S. submarine crew’s efforts to retrieve an Enigma encryption device from a disabled German submarine. After the crew gets the device, a German vessel torpedoes and sinks the U.S. submarine. The survivors must now use the disabled German submarine to escape from the enemy with their prize. The film’s almost nonstop action and extraordinary special effects look and sound best with a home theater system.
