It was ten o’clock, solar time, when disaster struck. At exactly the same moment, gravium mines on Mercury, Mars and Saturn were totally destroyed by an unidentified army. Without gravium – the life-blood of interplanetary civilization – the system would perish.

Captain Future -great enemy of evil- is called on to save humanity
James Carthew, President of the Solar System, watched from the government tower, his face lined with worry. Outside thousands of people were demonstrating. Once loyal citizens, they now urged Carthew to yield his power to a diabolic stranger named Dr. Zarro – a being from another mysterious system who had hypnotized the entire population with fear.
Carthews knew that Zarro would surely destroy humanity, but how could he prove it? There was only one man who could – perhaps – help him.
