Sci-fi thriller in which a 1980s warship is transported back to the Second World War. In 1980, the US Navy's most powerful warship, the USS Nimitz, is caught in a storm during routine manoeuvres in the Pacific. Enveloped by a strange green light, the ship passes through a vortex and when it emerges, the crew finds that all communication has been cut off. When Captain Matthew Yelland (Kirk Douglas) sends out a patrol, his F-14 pilots are shocked to encounter vintage Japanese warplanes. To their surprise, they discover that they have somehow been transported back in time to 6th December 1941: the day before the Japanese attack on Pearl Harbour. As captain of a technologically superior craft, should Captain Yelland fulfill his duty to protect the United States and foil the impending attack - or let history run its course?
