“In the Hawaiian Islands, an international naval fleet at Pearl Harbor engage in a dynamic and intense battle against an alien race known as “The Regents”. The aliens come to planet Earth on a mission to build a power source in the ocean. Upon their visit, they come in contact with the naval fleet. The film is also purported to show both sides of the story, from the aliens’ perspective, as well as the humans’ so the audience knows exactly where the opponent’s ships are.”
