Espionage and depth charges were not on the agenda for marine archeologist Dr. George Washington when he left the harbor that morning. While searching for a sunken vessel containing a secret shipment of lost Nazi gold, he witnessed a meteor crash to earth. The impact opened a time gate which propelled him back to World War II where he has been taken aboard an American submarine and imprisoned as a spy. Faced with an execution, he reveals to the sub commander he knows the allies have broken the German code Enigma. Dr. Washington comes to the realization he did not travel back in time; the sub traveled to the future and is manned by German impostors. With the knowledge their valuable code has been broken, the Germans head back through the time gate to 1943.

George must now journey to the past and stop this rogue submarine from altering the outcome of the war. While trapped in an era and a war he had only experienced from watching the History Channel, Dr. Washington is forced to kill his grandfather in order to stop the enemy operatives. His life and the war suddenly take a turn he never expected.
