It is the dawn of the 21st century. Mankind has terraformed and colonized Mars. But we are not alone in the universe. An ancient race of alien beings, known only as 'The Gods', has been watching mankind's progress and waiting. Now, these mysterious aliens have returned to halt mankind's expansion into space - by force. This movie tracks the exploits of a new experimental land battleship, called the Aeoba, with a battle hardened captain in their fight against a mysterious and impregnable fortress that is slaughtering the humans in this war. The battle sequences are done on such a fashion as to let you realize that there is an entire war going around and that even though the characters we are following have an important part in it, they are a far cry form the only ones involved.
