An emergency space docking goes wrong and the core of the orbiting Spacehub transit terminal goes into meltdown. A young traffic controller named Conrad is trapped inside and Alan is unable to reach him. With Thunderbird 3 being used to keep Conrad alive International Rescue's only hope is to modify Thunderbird 2 for space flight in order to transport a new cooling system to the hub.
