Earth is faced with annihilation by the Purple Dawn - effect of the cosmic fall-out from the swirling planet-in-the-making Polarthanus. Kemlo and his Space Scouts are out in the void, towing a crippled space ship with their scooters, when suddenly the crisis is upon them. The space-born boys have to make a decision: if they take drastic action will it avert the danger - or will they blow up Earth, the Satellite Belts and themselves?
