Mother Earth has been turned into an environmental wasteland by careless humans. Now, the human race has one last chance to save the Earth... With your help.

The United Star Cluster of Leezaluth, the governing empire of the Galaxy, has sent a warning to the Earth: "To any surviving Humans - An intergalactic terrorist group known as Gulfer is planning to invade your planet and use your polluted waste to build weapons. You Humans must stop Gulfer, or we will be forced to supernova your Sun and destroy the Earth to stop them. But if you can stop Gulfer, we will give you a new planet like Earth to live on."

Unfortunately, Earth can no longer afford to maintain a standing army or military. But there is still one brave hero willing to fight for the survival of Earth. He is Dan Dare, a young ace-pilot. Alexis, the messenger from Leezaluth, was awed by Dan's fighting spirit and decided to stay with him. She modified Dan's spacecraft and is now the navigator of the TOZ weapon system on Dan's ship.

The last epic struggle for the survival of the Human Race and Mother Earth has just begun... All our fates rest in your hands.
