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.
Meanwhile, Captain Future struggled on the floor of a moving space craft, his arms and legs bound by steel ropes. He did not know why he’d been captured – only that the system was in grave danger – that he was needed…
As Captain Future was plunged through space, towards a deadly orb of flaming gases – the raging inferno of the sun – he planned his daring escape. It was to be the most dangerous gamble of his life.
